[9/9] stash show: learn stash.showIncludeUntracked

Commit Message

Denton Liu Feb. 2, 2021, 9:33 a.m. UTC

The previous commit teaches `git stash show --include-untracked`. It
may be desirable for a user to be able to always enable the
--include-untracked behavior. Teach the stash.showIncludeUntracked
config option which allows users to do this in a similar manner to
stash.showPatch.
