It's not the purpose of a CUI program to dictate its environment, but rather to make the best efforts to behave in the context its creator have(th) given it... (including console, input/output stream...)
it means that running a CUI program (let's call it foo):
wine foo => will use a a very primitive console (as if foo's output was printf:ed on stdout, and foo's input was read on stdin). no fancy support (like cursor pos, colors, scrolling...) will be available
wineconsole foo => will use the ncurse backend of wineconsole (on current terminal) and will provide a full featured console
I'll provide a bit later a way (for those who really like the user backend) to use it the same way as wineconsole foo (yes, don't always believe what's said on wine-devel, those people exist !!)
let's start with wcmd

ChangeLog:
- don't create a new console upon startup
- no longer assume we're always attached to a console
