Looks very good, especially the part that mentions "in the local
repository". It seems to be a common novice misunderstanding what
`master@{one.week.ago}` means, and it might be beneficial to be more
verbose by saying "where master used to point to one week ago in
this local repository".

Just like "expire", "delete" should be accompanied by the same
"typically not". I do not think it is even worth mentioning that it
exists merely as an implementation detail for likgit:git-stash[1]
and for no other reason.

I think this started from a hope that these two share many, but
looking at the result I notice the shared ones are a tiny and
trivial minority. It probably makes sense to retitle this section
"Options for expire" (and remove "For the expire command only"), and
add an "Options for delete" section immediately after it that looks
like:
Options for `delete`
~~~~~~~~~~~~~~~~~~~~
--updateref::
--rewrite::
--dry-run::
The `delete` command takes these options whose
meanings are the same as those for `expire`.

Thanks for being complete, but I sense that it may be time we
switched to parse-options here, which gives us the help string for
free. Perhaps throw in a comment line before this hunk
/* NEEDSWORK: switch to parse-options */
or something to leave hint for other people?
Thanks.
