2008-02-21 Alexander Larsson <alexl@redhat.com> * gfile.[ch]: * gio.symbols: Add new g_file_has_prefix that does the same as g_file_contains_file. Deprecate g_file_contains_file and add a macro that converts it to g_file_has_prefix. The reason for this change is that the contains_file() name seems to imply that this does more work than what it does, but its really only a name match (from #517086) * gdummyfile.c: * glocalfile.c: * tests/g-file.c: Update to match the above change. svn path=/trunk/; revision=6546
