Same fix as the tcp stream. (stream_write): Again here. Just like tcp
2002-05-02 Jeffrey Stedfast <fejj@ximian.com> * camel-stream-fs.c (stream_read): Same fix as the tcp stream. (stream_write): Again here. Just like tcp stream's stream_write(), also make sure to save errno before calling fcntl to restore the fd flags. * camel-tcp-stream-raw.c (stream_read): Handle EINTR errors for select(). (stream_write): Same and also preserve errno when setting the fd flags back. If w == -1, return -1. svn path=/trunk/; revision=16673

* camel-mime-utils.c (header_decode_mailbox): Fixed the fix for
stupidly-broken-mailer bug #5 to work when multiple unescaped
characters were in a row. Fixes bug #24140.
