Chris Custine commented on FELIX-1803:
--------------------------------------

Merged various forks and added some ansi control character handling to allows 
multiline command editing and backspace across multiple lines.  Also fixes 
problems with redisplaying multiline commands while scrolling command history.

The hack to AnsiWindowsTerminal might be better off as a static method call to 
jansi AnsiConsole, but this will keep us from doing a new release of jansi just 
for this fix.  Some of this will also be better if integrated directly into 
jline as Jason Dillon is apparently doing in his jline 2.0 branch.

> Multiline commands are screwed up in general.  Unable to edit/backspace 
> beyond first char of last line, and multiple line commands screw up display 
> of history using up/down arrows.  This is mostly a jline issue, but since we 
> have our own fork and have specific terminal types we use, I am creating an 
> issue here to track the fix.
