Reset filter on setup. (reset): When resetting qp encoding, set the state
2000-07-13 Not Zed <NotZed@HelixCode.com> * camel-mime-filter-basic.c (camel_mime_filter_basic_new_type): Reset filter on setup. (reset): When resetting qp encoding, set the state to -1, instead of 0. * camel-mime-utils.c (quoted_encode_step): Actually count the characters output sofar (it never counted any). Bunch of other fixes. (quoted_encode_close): Also flush out final character, if ther's one. svn path=/trunk/; revision=4135
