source: storage_text.c @ f06894d

Last change on this file since f06894d was 7e3592e, checked in by Wilmer van der Gaast <wilmer@…>, at 2006-07-05T18:34:31Z

Fixed text_load(), added detection of primary storage backends without
save support (which shouldn't be allowed) and added a call to nick_lc()
to xml_save() so at least nicks should now be case-insensitive.
