Use the byte-read count to decrement the number of bytes left to read
2000-11-17 Jeffrey Stedfast <fejj@helixcode.com>
* providers/imap/camel-imap-command.c (imap_read_untagged): Use
the byte-read count to decrement the number of bytes left to read
rather than using strlen. Not only does this protect against a DoS
(embedded NUL chars in the literal string would make strlen
inaccurate) but it also improves performace a little.
* camel-remote-store.c (remote_recv_line): *Sigh* Return the
number of bytes read on success rather than 0. Also don't use
camel_stream_buffer_read_line since we can't get an accurate octet
count.
