Summary: winetty driver wrecks console output
           Product: Wine
           Version: 20050111
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: wine-x11driver
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

- winetty seems to use ncurses for simple line-oriented output where winex11  
did the right thing and didn't wrap the output with escape sequences in such  
a weird way

- winetty clears the screen upon startup (due to ncurses maybe), so e.g.  
running things from nmake.exe makes the screen get wiped everytime a  
compile/link step is invoked.

This has a nasty side effect: with winetty driver a simple 
wine foo.exe > log 
gives you corrupt output with escape sequences that weren't reallyoutput by  
foo.exe , whereas with winex11 
wine foo.exe > log 
gives you the *correct* output capture.

I presume there should be a way in ncurses to preserve current console 
contents, for one. It'd be also desirable to only insert escape sequences when 
cursor movement is actually called for by the application itself by doing 
console buffer writes at locations that aren't at the current cursor position.
