Description Ralph Giles 2009-07-23 12:54:59 UTC 
Debugging the msvc build of gxps circa r9883, I discovered a segfault in
pjl_check_font_path(), which was assuming gs_enumerate_file_next would fail if
passed the return value of gs_enumerate_files_init(), even if the later returned
NULL to indicate failure.

This was fixed in r9884, but I think it's worth checking the arguments in the
implementations as well. The extra conditional isn't expensive relative to
talking to a filesystem, and we'll gain much better error recovery elsewhere.

Closing, it isn't exactly clear what is being requested in the initial description.
