mdfrm is a simple mail reporting program inspired by elm's frm
program.  Whereas elm's frm operates on Berkeley mbox files, mdfrm
operates on maildirs.  It prints one line for each message in
Maildir/new, first the From header and then the Subject header.

mdfrm makes use of fgetln(3), which as far as i can tell is only
available on BSD.  To make this easy to use on other UNIX-like
platforms, i have copied Marc Espie's portable implementation from
OpenBSD make(1).  See fgetln.c for details.
