Be more careful about echo_buf arithmetic, event-stream.c.
src/ChangeLog addition:
2015-03-12 Aidan Kehoe <kehoea@parhasard.net>
* event-stream.c (lookup_command_event):
Check whether echo_buf_fill_pointer is negative before using it in
arithmetic, avoiding a crash in GC.
Oddly the old code didn't do this check and didn't crash, but its
echo_buf was from malloced memory, not from our string data, so
there may have been more room to manoeuvre.
