Updates for compliance with rfc2231
2001-11-19 Jeffrey Stedfast <fejj@ximian.com> Updates for compliance with rfc2231 * camel-mime-utils.c (header_encode_param): camel_mime_special_table[c] & IS_ESAFE should have been !(camel_mime_special_table[c] & IS_ESAFE). Also added a few comments for how to improve the code at some future date. (header_decode_param): Now takes an argument rfc2184_part so our caller can get this information as well. (header_decode_param_list): Pass an rfc2184_part argument to header_decode_param and also added a few comments on where to improve on rfc2184/rfc2231 compliance. (rfc2047_decode_word): Updated to respect the updated ABNF syntax of rfc2047 encoded words, yay. svn path=/trunk/; revision=14750
