Problem with office Installer and filename resoloution.

[Matthew Davison]

The installer fo Office XP i broken in recent CVS. IT returns an error
stating that a file does not exist, when the file in question blatantly
does exist. After further investigation, it appears that the installer is
trying to open "osp.msi " (note the trailing space) MSDN states that such
trailing spaces are not supported, and it appears that windows simply
removes such spaces when added to a filename. This has been confirmed by
making a copy of the file with a trailing space in linux and then the
installer finds it correctly. I am assuming this has something to do with
the recent changes to the filesystem code, and am unsure how to fix this
myself.
