• Reduced flicker when async prompt filtering redraws the prompt.
• When _argmatcher:addarg() or _argmatcher:addflags() is passed a table containing nowordbreakchars="chars" then the chars are not treated as word breaks for that argument index or for flags (see Overcoming Word Breaks for more information).
• Added a user_data argument to the custom classifier function for an argmatcher (set via _argmatcher:setclassifier()).
• Improved input line coloring for clink set so that color.unexpected is only used for a completed word that isn't a match.
• Fixed reading lines from stdin in Lua scripts (e.g. io.stdin:read()).
• Fixed accidentally showing matches in a single column sometimes even when there are no descriptions.
• Fixed an incomplete clink inject if an explicit or implicit endlocal happens after clink inject but before the prompt is shown (the injection didn't finish successfully until the next time an environment variable was set, but now it finishes immediately).
