Hmm.

Is there anything that describes how <stash-like>, <stash-entry> and
<stash> relate to each other?  I do not think a regular reader can answer
by reading the description after the patch these questions:

 - Is a <stash-entry> a <stash-like>?
 - Is the opposite true?

etc...

Perhaps we can simply call these two-parent merge commits a <stash>,
define that these commands as working on a <stash>, add notes to certain
subcommands that the <stash> they take must be on the stash ref (as
opposed to a freestanding one you can create with "stash create"), and be
done with it?

Also what is the error condition?  I am assuming that your <stash-entry>
is a <stash-like> that is on the reflog of refs/stash, but if you give a
<stash-like> that is not a <stash-entry> (iow a freestanding <stash>) to a
subcommand that wants to see <stash-entry>, what happens, and does the
document describe it as an error?
