   - ble-core.sh (ble/util/joblist): bugfix: add ble/util/joblist.clear
     bash 自身によってジョブ状態の変化が報告された後に、
     二重に状態変化が報告される場合があるので、その様な場合にはキャッシュを消去する。
   - ble-edit.sh の各 jobs を呼び出すところで、ble/util/joblist を代わりに呼び出す。
   - ble-syntax.sh, ble-color.sh で jobs を使用してジョブの存在確認している箇所では、

 ## 2016-07-05

   - 2回目以降の ble-attach でも ble-decode-bind/uvw が動作する様に
     ble-decode-attach で source "～.bind" した直後に _ble_decode_bind__uvwflag をクリアする。

 ## 2016-05-21
 * update README.md for v0.1.5
 * ble-edit.sh: bugfix, incorrect _ble_edit_ind caused by the inconsistensy of history/isearch targets.
   - _ble_edit_history を履歴検索して _ble_edit_history_edit をロードしていた事による _ble_edit_ind 不整合
     これにより、dirty-range の不整合が生じエラーが発生していた。長年の謎のバグがこれで潰れたと思われる。
 
 ## 2016-04-07
 * ble-syntax.sh (ble-syntax/parse/shift.impl2): bugfix 制御構造の欠陥による shift 漏れ。

 * (ble-color/faces): preserve orders of addhook-onload, and ble-color-{def,set}face.
   - ble-color/faces 初期化前に呼び出した ble-color/faces/addhook-onload,
     ble-color-defface, ble-color-setface を独立に記録していた為、
     実際に呼び出された順序と異なる順序で処理が実行されてしまっていた。
     記録を一つの配列 _ble_faces_lazy_loader にまとめ、順序が保存される様にした。
 
 ## 2015-12-25
 * (ble-color) \change ble-color-{def,set}face の処理も遅延する。
 * functions/getopt.sh: \add description.
 
 ## 2015-12-24
 * (ble-syntax:bash): :new:, support option `-p` for keyword `time`.
 * (ble-syntax:bash): \new, support `a=([key]=value)` and `a+=([key]+=delta)`.
   * (ble-syntax): \new local variable `parse_suppressNextStat` in ble-syntax/parse.
   * (ble-syntax:bash): \bugfix, correct resume for `var+`, `arr[...]+` -> `var+=`, `arr[...]+=`.
   * (ble-syntax:bash): \new, support `a=([key]=value)` and `a+=([key]+=delta)`.
 * (ble-syntax:bash): \new context CTX_CASE.
 * (ble-syntax:bash): \new CTX_COND{X,I}; \change unexpected '(' is treated as extglob '@(' instead of sub-shell '(';
   * ble-syntax.sh: `CTX_VAL{X,I}` から `CTX_COND{X,I}` を分離。
   * ble-syntax.sh: コマンド中に現れる '(' を extglob の括弧として取り扱う事にする。
     今迄は暫定的に sub-shell として取り扱っていたが、
     エラーが多く出てうるさいのでエラーの少ない extglob 括弧として取り扱う事にする。
 * ble-edit.sh: \bugfix histexpand condition [[ -o histexpand ]] inverted.
   * \bugfix 履歴展開が効かなくなっていた。
     条件判定の誤りだった: [[ -o histexpand ]] → [[ ! -o histexpand ]]
   * \bugfix 履歴展開に失敗した時に : が実行される。
     履歴展開が失敗すると history -p は標準出力に何も出力しないためであった。
     失敗した時は echo "$BASH_COMMAND" により手動で出力する。
 * (ble-syntax:bash): \support shopt -s extglob; \bugfix error on {delimiter after redirect,'<' redirect};
   * extglob 対応: `CTX_GLOB`, `ATTR_GLOB`, `ctx-glob`, `check-glob` 追加。
   * \bugfix redirect 直後に redirect/delimiter があった時に解析データ書き込み違反。
   * \cleanup: 共通の正規表現の整理:
     `$_ble_syntax_bash_rex_spaces`,
     `$_ble_syntax_bash_rex_IFSs`,
     `$_ble_syntax_bash_rex_delimiters`.
   * \bugfix `$_ble_syntax_bash_rex_redirect`: < が抜けていた。
 
 ## 2015-12-23
 * (ble-syntax:bash): special treatment of arguments of `declare`.
   * (ble-syntax:bash): declare, typeset, local, export, alias コマンドの引数を文法的に特別に扱う。特に配列構文 =() を許容する。
     その為に新しい文脈値 `CTX_ARGVX`, `CTX_ARGVI` を追加する。
   * (ble-syntax:bash): `CTX_ARGVI` に対する補完候補は変数名。等号 '=' 以降の部分についてはファイル名の補完候補を列挙する。
   * (ble-syntax:bash): 通常の代入構文における配列構文の動作を変更。
     今迄は a=(1 2 3)echo などとすると a=(1 2 3) を配列代入と解釈し echo の部分をコマンドと解釈する様にしていた。
     その為に配列構文の nest-pop 時にすぐに単語を抜けて cxt==CTX_CMDXV になる様に構成していた。
     しかし、実際の bash の動作を確認してみると、a=(1 2 3)echo は a='(1 2 3)echo' の様に、全体が代入文の右辺と解釈される様である。
     実際の bash の動作に合わせて、nest-pop 時に特別な動作を特にしない様に変更した。
 
 ## 2015-12-21

     ${var:...:...} では '}' が来たらすぐに終了する。
   * ble-syntax.sh (completion-context): a+= の直後でも補完候補生成を行う。
   * ble-syntax.sh (ble-syntax:bash): disable += under bash-3.1.

   * ble-edit.sh (ble-edit/dirty-range): 範囲更新の仕組みを追加。
       _ble_edit_dirty はプロンプト再描画の判定も兼ねているので取り敢えず残す。

   * ble-syntax.sh (ctx-command/check-word-end): 単語終了判定の処理タイミングを変更。
   * ble-syntax.sh: context の追加。CTX_CMDXF CTX_CMDX1 CTX_CMDXV CTX_ARGX0
     より正確な文脈判定・エラー検知。
   * ble-syntax.sh: 他にも多くの修正がある。未だ修正が続きそうなので一旦 commit する。
 
   * ble-edit.sh (accept-line): bug, - で始まるコマンドを実行できない。

 ## 2015-02-16
   * ble-syntax.sh: bugfix, incremental に更新した時に word の長さが更新されない。
     _ble_syntax_word への格納の際に失敗していた。
 
 ## 2015-02-15
   * ble-synatax.sh: bash の文法に従った incremental な解析と色付け。
 
 ## 2015-02-14
   * ble-edit.sh (.ble-line-info.draw): 表示が遅いので修正。
     ASCII 文字は特別扱いする様に改良。劇的に速くなった。
 
 ## 2015-02-13

   * ble-edit.sh (.ble-edit/gexec): グローバルな文脈でコマンドを実行する仕組み。
     再帰呼出に対する C-c にも対応。bleopt_exec_type で実行の方法を切り替えられる様に。
     exec が従来の方法で gexec がこの新しい方法。
 
 ## 2015-02-12
   * ble-decode.sh: bugfix, exit 後に stty が壊れているのを修正
     これに伴って ble の detach 機能の実装も行った。
   * ble-decode.sh: bugfix, bash-4.3 で三文字以上のシーケンスが悉く聞かない。
     keymap が見付からないエラーになってしまうので全てのシーケンスについて bind -x する事にした。
   * ble-core.sh: bugfix, builtin printf \U.... の使えない環境で command printf fallback が働かない。
     printf のパスを修正。また ASCII に対しては printf は使わない様に変更。
   * ble-color.sh (ble-syntax-highlight+default):
     追加・修正。また選択範囲の反転を ble-syntax-highlight+region として実装し、それを呼び出す形に。
   * ble.pp: 起動時に interactive モードかどうかのチェックを行う様に。
 
 ## 2015-02-11
   * ble-edit.sh (_ble_edit_io_*): ちらつきを抑える為に stdout/stderr を切り替える事にした。
     ちらつくのは bash の既定の出力によって ble の表示がクリアされ、bash の表示したい物が表示されるから。
     これに対抗して ble は bash の出力の直後に上書き再描画して何とか表示していた。
     bash の既定の出力を抑える為に、exec で出力先を切り替える事にした。
     bash の出力はファイルに書き込まれる様にし向ける。出力先ファイルを逐次確認して、
     エラーが出力されていれば visible-bell で表示する事にした。
     `bleopt_suppress_bash_output=1` の時にこの新しい方法を実験的に用いる。
     `bleopt_suppress_bash_output=` の時は従来のちらつく方法。
 
 ## 2015-02-10
   * ble-edit.sh (accept-line.exec): bash-4.3 で内部からグローバル変数を定義できる様に
     declare 及び typeset を上書きして -g オプションを指定する様に変更。
     また、これに関係する注意点を ble.htm に記述。
   * ble-edit.sh (history): ロードに時間が掛かるので最適化。
   * 全般: bugfix, 文字列分割で GLOBIGNORE='*' を設定していないとパス名展開されて危険
   * ble-color.sh (ble-syntax-highlight+default): より良い色づけ。
   * ble-edit.sh (accept-line.exec): ble-bind -cf で bind されたコマンドの実行コンテキストを変更。
     accept-line で実行されるのと同じコンテキストで実行する。
   * ble-edit.sh (keymap default): C-z M-z を fg に bind。
 
 ## 2015-02-09
   * git repos
   * ble-edit: bugfix, locate-xword マクロが展開されていなかった
   * ble-decode: bash-4.3 に対応する為に色々変更
     - bind 指定の場合分けを整理
     - bugfix, ESC ?, ESC [ ? に対して全て bind
     - bugfix, 場合によって全く bind -r できていない
       →"bind -sp | fgrep" が "バイナリ" という結果になる事がある様だ。
         fgrep に -a を指定する。
     - bugfix, 日本語が入力できない。8bit 文字が認識されない。
       →8bit 文字はエスケープシーケンスで bind に指定する様に変更。

   * highlight.sh: 取り敢えず簡単な色付け
   * ble.sh:
 
     -- 経緯 --
     highlight.sh の方針だと bash が表示する編集中の内容を消す事が出来ないし、
     カーソルの位置も bash が表示する物の場所を指している。
     色を付けて表示した物は、補助的に bash が表示する物の下に並べて表示する
     ぐらいしか方法がない。
 
     また readline 関数をスクリプトから呼び出す事が出来ないので、
     結局、色付けを更新したいタイミングで READLINE_LINE や READLINE_POINT の動作を
     スクリプトの側で全て模倣して再現しなければならない。
     READLINE_LINE, READLINE_POINT の bash の仕様が変な所為で、日本語など
     のマルチバイトで正しく処理する為に、色々と汚い事をしなければならない。
 
     以上の事から、文字列の編集などの操作からスクリプトの実行まで
     全部自分で好きな様に実装して bash readline の機能を全て上書きする事にした。
     その為に、スクリプトを新しく書き直す。zle を真似て ble (bash line editor)
     と名付ける。
 
     -- 方針としては --
     a. read -n 1 を用いて 1 文字ずつ標準入力から文字を取り出してそれを処理していく
     b. bash の bind で全ての文字に ble のバイト受信関数を繋げて、
        バイト列を受信しながら処理する。
 
     highlight.sh の延長線上で b. の方針にしたが、
     もしかすると a. の方針も可能かも知れない。
 
 ## 2013-05-29
   * highlight.sh: 作成
