[Bug 10472] New: File open dialog buffer too short for multiple file selection

http://bugs.winehq.org/show_bug.cgi?id=10472

Summary: File open dialog buffer too short for multiple file
                    selection
           Product: Wine
           Version: 0.9.49.
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: wine-comctl32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

The file open dialog seems to be using a buffer which is too short for multiple
file selection. While Windows itself has this bug/feature, wine's version is
much more annoying since I'm unable to select over 6 files usually (using long
but not excessive names).
A dynamic buffer (with a reasonable limit for security reasons perhaps) would
be preferrable, but even a bigger buffer would help. 
I think windows' buffer is 4k.
