release-1.8release-1.9
Last change on this file since c6332f5 was dde1b4d, checked in by David Benjamin <davidben@mit.edu>, 10 years ago
Use g_build_filename instead of g_strdup_printf to build paths Saves us a duplicate slash in a few places, although most of the time it doesn't do anything. Eh, may as well use it and be more explicit or something. Also change the one existing call to g_build_path to g_build_filename instead. It's much less of a pain to use.
