Log Message:
Update fdm to 1.7.
Based on PR pkg/48254 by Leonardo Taccari.

pkgsrc changes:
 * add options.mk: now fdm supports "debug" and "pcre" \ 
options (previously the
   PCRE support was always included).

Changes:
 * Add mbox tags for messages fetched from a mbox
 * Detect GMail's XYZZY capability for IMAP and use it to try and workaround
   some of their broken behaviour (incorrectly reported message sizes).
 * Print a warning on missing maildirs when fetching from them rather than
   crashing or giving an error. Reported by Frank Terbeck.
 * Introduce a configure script and tidy up build infrastructure.
 * GMail IMAP doesn't correctly set the \Seen flag after UID FETCH BODY[], so
   explicitly set it with STORE when mail is kept. Reported by Patrice Clement.
 * Properly count mails when polling multiple folders on a single IMAP server,
   reported by Claudio M. Alessi.
 * Support user and pass on NNTP, requested by Michael Hamann.
 * Escape . properly when delivering to SMTP.
 * Don't be as strict about format at the end of messages when using IMAP -
   accept additional information as well as FLAGS. Reported by rivo nurges.
