 - main: export `BLE_SESSION_ID` `#D2188` 5871fea2
 - menu-complete: adjust cursor position with `insert-selection` disabled (reported by gvlassis) `#D2206` xxxxxxxx
 - decode (`ble-bind`): do not convert registered C0 (motivated by gvlassis) `#D2210` xxxxxxxx
+- decode (`ble-bind`): support combined option arguments of the forms `--long=OPTARG` and `-kOPTARG` `#D2211` xxxxxxxx

+  * decode(ble-bind): combined options 対応 [#D2211]

+    #D2210 の対応中に気になったが #D2210 の中に含めるには大きいので分ける事にし
+    た。実際 #D2210 の変更とは overlap が全くない。簡単にテストした。

   * decode (ble-bind): ble-bind -k TAB TAB で TAB をそのまま透過する様にできたら良い気がする (motivated by gvlassis) [#D2210]
