Yay, a documentation update. Should it be s/references/referenced/ in
the second-to-last line?

This seems whitespace damaged, though.   I see a few   at the
beginning of lines.

Also, Aaron, next time please refrain from reflowing the paragraph
unnecessarily.  I am guessing that you only added one sentence at
the end of an existing paragraph, and such a patch should clearly
show that the only change it did is to append at the end.  Reflowing
will force reviewers to compare the preimage and postimage word by
word to spot what other things were changed.

So I don't think this is technically a regression in any
currently-functioning behavior, but it seems like a step in the wrong
direction to add yet another layer of blind parsing.

Yes.  I agree that the implementation of this patch goes in the
wrong direction, even though it means well.

Double yay, tests.

Do we really need a whole new script for this, though? There are already
"stash show" tests in t3903. We should be able to repeat one of them
using "2" instead of "stash@{2}" (for example).

Yes, it seems a lot better direction to go.  The existing script
t3903 may want to see a bit of modernization clean-up before that to
happen, though.

Thanks for a review.
