credential: handle partial URLs in config settings again (master)

This is a companion patch to https://github.com/gitgitgadget/git/pull/615,
but targets maint instead of maint-2.17: There is not really a good way to get those patches into maint by merging because the final patch looks quite a bit different by necessity (after 46fd7b390034 (credential: allow wildcard patterns when matching config, 2020-02-20) the urlmatch machinery is supposed to handle credential.<url>.* config parsing).

IMHO the easiest strategy would be to apply these patches on top of maint, then merge the other patches on top of maint-2.17 with -s ours.

Note: typically I do not send GitGitGadget PRs before the builds finished, just in case that I did something really stupid that breaks plenty of tests. However, in this case, I figure that y'all want to see them patches early, and I can't wait for the build to finish because I need to get some rest, like, right now.

Johannes Schindelin (2):
credential: optionally allow partial URLs in
credential_from_url_gently()
credential: handle credential.<partial-URL>.<key> again
