Please don't remove the Cc list, it helps us (among other things) flag
the mail that is important.

Not sure.  I personally prefer the behaviour as it is now, as I have
status.showUntrackedFiles = no and would most likely forget about
them.  It has been that way since the introduction of git-stash, so
maybe Nanako (Cc'd) can enlighten us further.

That being said, it could probably be made configurable along the
lines of the patch below, or even with a config option.
