v1.5.6

• Added os.getpushddepth(), which works when %PROMPT% contains exactly one $+.
• The clink-popup-history and win-history-list commands show timestamps when history.time_stamp is set to show.
• Fixed os.geterrorlevel() when cmd /u was used.
• Fixed word break parsing in the input line when certain Unicode characters are present.
• Fixed Unicode string conversions to disallow translating to "similar" characters (which could be problematic in filenames).
• Fixed a crash in rl.getkeybindings() if it's called by a Lua script running inside clink set.
• Fixed Lua debugger input if a script error occurs inside clink set.
• Fixed a width quirk in clink-select-complete where typing to narrow the list to a single item accidentally made the column width at least 3 characters, even if the item was only 1 or 2 characters width.
• Fixed clink history to handle escape codes embedded in the history.time_format setting.
• Fixed a potential crash after using remove-history at the beginning of the history list.
• Fixed #494; Lua error when using unicode.fromcodepage() (reported and fixed before the bug was published).
• Fixed #493; clink-select-complete displays the selected item incorrectly if both colored-stats and colored-completion-prefix are off (regression introduced in v1.5.5).
