[Bug 9394] New: Work folder on ShellExecute and CreateProcess

http://bugs.winehq.org/show_bug.cgi?id=9394

Summary: Work folder on ShellExecute and CreateProcess
           Product: Wine
           Version: 0.9.33.
          Platform: Other
        OS/Version: other
            Status: UNCONFIRMED
          Severity: trivial
          Priority: P2
         Component: wine-shell32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

I used to make some windows app , I tried to make them work correctly on WINE,
noticed gltiches and things that made me unable to use them.

They rely heavily on executing other programs, that's where the problem comes
from, I as a winapi developer made some mistakes that didn't stop the apps from
working correctly in winapi but affected them on WINE.

Specifically the work folder (current directory/directory) arguments in both
ShellExecute and CreateProcess :
- WINE and winapi support ".\" correctly.
- WINE however does not support "." while winapi does.
- Apparentally WINAPI accepts NULL and assumes it means ".\" but WINE does
not.

After fixing the code in my apps to use ".\" there they began to work
correctly, I figured this bug may affect some other applications so I am
reporting it.
