Summary: wcmd: command piping broken
           Product: Wine

          Platform: PC-x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: enhancement

Hi there,
still trying to get KDE4/win32 compiled under WINE... the python glitches went
away by creating a fresh .wine directory, however another problem came up:
piping is broken in wineconsole. F.e., dir | more results in this:

C:\kderoot\emerge\bin>dir | more
trace:cmd:WCMD_DumpCommands Parsed line:
trace:cmd:WCMD_DumpCommands L"0012F6E8 N 00 00000000 dir  more Redir:"
trace:cmd:WCMD_process_commands Executing command: 'L"dir  more"'
trace:cmd:WCMD_execute command on entry:L"dir  more" (0x33f5d0), with
'(null)'='(null)'
trace:cmd:WCMD_execute Command: 'L"dir  more"'
trace:cmd:WCMD_execute param1: L"more", param2: L""
trace:cmd:WCMD_directory Found parm 'L"more"'
trace:cmd:WCMD_directory Using location 'L"C:\kderoot\emerge\bin\more"'
trace:cmd:WCMD_directory Using path 'L"C:\kderoot\emerge\bin\more"'
trace:cmd:WCMD_directory Path Parts: drive: 'L"C:"' dir:
'L"\kderoot\emerge\bin\"' name: 'L"more"' ext:'L""'
trace:cmd:WCMD_directory Writing volume for 'C:'
Volume in drive C is
Volume Serial Number is 0000-0000

trace:cmd:WCMD_list_directory Looking for matches to
'L"C:\kderoot\emerge\bin\more"'
Directory of C:\kderoot\emerge\bin

File not found

trace:cmd:WCMD_dir_trailer Writing trailer for 'L"C:\"' gave 1(87)
C:\kderoot\emerge\bin>

so obviously, the '|' is lost somewhere and 'dir more' is what gets executed...
output redirection into a file with '>' works as expected. I had a look at
wcmdmain.c but I could only narrow down the problem to be somewhere within
WCMD_ReadAndParseLine and WCMD_pipe so any further investigation would be
appreciated.
