Fix for 687151, gswin32 starts with 7s delay..., improved log message

This is a improved log message for a bug fix submitted earlier.
http://www.ghostscript.com/pipermail/gs-code-review/2003-December/004295.html

LOG MESSAGE:
On MS Windows convert filenameforall template string back to the path
name discarding literary status of \*? because it is not supported by
the API. OS/2 probably needs the same fix.

DETAILS:
This shoud fix the reported problem but a general solution need much
more efforts, including:

(1) Use of platform-independent path names in the template. I.e.
      consider '/' as a path separator on any platform and map it
      accordingly.
(2) Support of '?' and '*' wildcards on the platforms which don't
      support them natively.
(3) Support of literary '\\', '?' and '*' on the platforms which don't
      support them natively.
(4) Recursive enumeration of the directory.

EXPECTED DIFFERENCES:
None
