I was using the gmane page, which did it. Next time I replied using
email, but forgot to add the CC. There are things I hate more than
mailing lists, but they're fairly rare.

OK, this is a sort of acceptable.

OK, the strange pattern matching is not that bad.

I wonder what
git show-ref --head
really does. It seems to output everything, is this the expected (albeit
strange) behavior? Maybe, I know now, s. below.

For sure, either the doc is completely wrong or the implementation. I
hope I understand "Show the HEAD reference" correctly as showing the
HEAD reference, don't I? So it must show a single reference (singular).
Instead I get all tags and all heads. Could anybody either fix the doc
or convince me that the many lines I'm seeing are a single one?

Shouldn't there be an option *really* doing what --head is expected and
documented to do? I mean something like
git show-ref --head --yes-I-really-mean-the-head
with the output consisting of a single line like
4ba2b422cf3cc229d894bb31c429c0c588de85c0 HEAD
Maybe it could be called --head-only.

It could help a lot to add the word "additionally" to the doc like
--head
Additionally show the HEAD reference.

I guess, I can get the single line I wanted using
git for-each-ref $(git symbolic-ref HEAD)
right?
