one. "get_basename()" doesn't modify its argument, and its callers don't modify the substring pointed to by the result, so make it take a "const char *" as an argument and return a "const char *". "find_last_pathname_separator()" doesn't modify its argument, so make it a "const char *" - but some of its callers pass a non-"const" "char *" and modify the result, so don't make its return value a "const char *". And, as none of its callers are outside "filesystem.c", make it static. In "about_folders_page_new()", have separate variables for pathnames returned as "const char *" (which are cached by the routine that returns them, so you can't modify them - and can't free them, so get rid of the commented-out "g_free()" calls for them) and pathnames returned as "char *" (which are allocated anew for each call, and can be modified, but have to be freed). Clean up white space. svn path=/trunk/; revision=12881
