>From a show buffer, notmuch-bbdb/snarf-from imports the sender into
bbdb.  notmuch-bbdb/snarf-to imports all recipients.  Newly imported
concacts are reported in the minibuffer / Messages buffer.

Both functions use the BBDB parser to recognize email address formats.
---
Following discussion upthread, I put everything in notmuch-address.  I
renamed the functions to put notmuch before bbdb.  And I replaced the
horrid comma-splitting from my first version with the functions BBDB
provides for parsing email headers.

It looks as though Reply-To is not exposed in the :headers plist.  I
assume the Resent-* headers are not, either.  Therefore none of these
are imported (nil entries in notmuch-bbdb/header-by-name).  They would be
easy to add if the plist is expanded.

Thanks, and sorry it's taken me so long to get back to this patch.
