lei q: SIGWINCH process group with the terminal

While using utime on the destination Maildir is enough for mutt
to eventually notice new mail, "eventually" isn't good enough.

Send a SIGWINCH to wake mutt (and likely other MUAs)
immediately.  This is more portable than relying on MUAs to
support inotify or EVFILT_VNODE.
