write-region fails with some filenames

[Dominique de Waleffe]

This bug report will be sent to the Free Software Foundation,
 not to your local site managers!!
Please write in English, because the Emacs maintainers do not have
translators to read other languages for them.

In GNU Emacs 20.7.1 (i386-*-nt5.0.2195)
 of Tue Jun 13 2000 on buffy
configured using `configure NT'

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

Trying to save or view a Mime attachment from VM I got the following
backtrace:

Signaling: (file-error "Opening output file" "invalid argument" 
"c:/users/ddw/projects/portima/admin/Work2001-11.3,4.xls")
  write-region(1 23553 
"c:/users/ddw/projects/portima/admin/Work2001-11.3,4.xls" nil nil)
  vm-mime-send-body-to-file(#<overlay from 1460 to 1534 in miscrit-mvb 
Presentation>)
  vm-mime-run-display-function-at-point(vm-mime-send-body-to-file)
  vm-mime-reader-map-save-file()
  call-interactively(vm-mime-reader-map-save-file)

I believe the comma triggers the problem in write-region.
