Done.

Done, but I went with symbol-name instead of format.

I had tried that originally, but map-keymap brings in data from parent
keymaps, which is undesirable in this case. There is a function
map-keymap-internal which might be a usable alternative, but it returns
a single unusable cruft element (the parent keymap) when it exists, so
the result doesn't seem much better than the current code, no?

Great catch. It solves the bug you found. Done.

As for posting updates to the code submission, I can do any combination of
the following, or something else, but want guidance before proceeding:

1) post to this list;

2) post to the pre-existing thread on emacs-bugs;

3) create a github repo, and post there (and gain potential wider
audience, more features, but fragment communication over two platforms);

4) create a repo on some imagined savannah / gnu server;

Finally: Tomorrow approaching sunset I go offline for about nine
days[1], so what I can squeeze in before then, great; afterwards I
welcome any continued feedback but please be patient and don't expect
any response for ~10-12 days.

But really finally this time: I've twice already made passing reference
to another package about ready to submit, that adds a lot of new
functionality to dired. I can post it now in its current state, and
inconsiderately disappear offline for 9+ days, or I could just as
inconsiderately not post it and deny you for 9+ days. I'm undecided, so
unless I hear otherwise, I'll wait.
