[PATCH v4 1/3] stash: fix nonsense pipeline

[Junio C Hamano <gitster@pobox.com>]

An earlier change bba067d2 ("stash: don't delete untracked files
that match pathspec", 2018-01-06) was made by taking a suggestion in
a list discussion [1] but did not copy the suggested snippet
correctly.  And the bug was unnoticed during the review and slipped
through.

This fixes it.
