... I do think the documentation should recommend "now". Possibly
builtin/gc.c should be smarter about recognizing "all" in the
conditional you quoted, too, though I don't know that it's all
that important (especially if we tweak the documentation).

Yup, as the placeholder for the value is labeled as "<date>", "now"
would be the one we should be encouraging.

  i can submit an obviously trivial patch for that

You already did to turn --prune=all into --prune=now in the doc, I
think.

Do we encourage 'false' where we should encourage 'never'?  I see we
do not even mention the negative form in git-gc manpage, and I think
it is a good thing, especially because --prune=<date> is listed just
next to --no-prune, which is even more explicit.
