git-stash needs to restrict itself to plumbing when running automated
diffs as part of its operation as the user may have configured a
custom diff driver that opens an interactive UI for certain/all
files. Doing that during scripted actions is very unfriendly to
the end-user and may cause git-stash to fail to work.

Does this fix the problem?
