Added some malloc check debugging stuff.
2000-10-17 Not Zed <NotZed@HelixCode.com>
* camel-mime-filter.c: Added some malloc check debugging stuff.
* camel-mime-parser.c
(struct _header_scan_state): Removed top_part, top_start, and
pending. I can't even remember why they were there, and they're
not used anymore.
* camel-mime-filter-basic.c (filter): Forgot to up the space here
too.
2000-10-14 Not Zed <NotZed@HelixCode.com>
* camel-mime-filter-basic.c (complete): Ok, so we hit a fixme, 3x
just wasn't enough for some sequences.
