[PATCH] replace gnu xargs usage in notmuch-mutt with perl

[Stefano Zacchiroli]

Hi Taylor, thanks for your patch. It makes sense to me, and has the
beneficial side effect of avoiding a sed pass to do some poor men shell
escaping.

Before applying, however, can you please update it to:

- include a reasonable comment (as suggested by David)
- avoid patching the shebang line (ditto)
- coalesce the sprintf() line into the following symlink line (using
  sprintf seems redundant here: it's plain string concatenation)

Thanks!
Cheers.

PS please Cc:-me on replies
