Use the new readline function.
2002-05-24 Jeffrey Stedfast <fejj@ximian.com> * providers/imap/camel-imap-command.c (imap_read_untagged): Use the new readline function. * providers/imap/camel-imap-store.c (connect_to_server): Use the new camel_imap_store_readline() function which doesn't suck quite as bad as the original camel_remote_store_recv_line() function. (camel_imap_store_readline): New function to replace camel_remote_store_recv_line(). This function is at least safe with embedded nul chars. Not that any of our callers use it *sigh*. svn path=/trunk/; revision=17012
