simple fix for "Unable to make version backup" warning when saving files. missing a return.

For *nix sustems, recent physics pointcache refactor uses stdio.h's remove() rather then system("rm -f ...") for removing files, since it was a lot slower for removing pointcache.

Ton used the system command because there was some problem using remove() ~6years back, but he cant remember why, (maybe its not a problem now)

Simple error, remove wasn't returning a value, but keep an eye out for problems removing files, and if anyone can reproduce the "Unable to make version backup" problem when saving, we should look into it.

Also added a note about using # in the output path for blenders command line help text.
