This matches the existing use of "got -r path cmd" and "git_commit path args".

As reported by naddy, this is a non-portable Korn shell construct. Instead, use the one argument array then make faux space-delimited string "arrays" for the other ids; they can still be indexed with pop_idx. improved by + ok naddy@

More work adding commit keyword support to the blame, cat, ref, tag, and tree commands. With this, all Got commands that take a <commit> option argument or operand now support keywords. Regress flub saved by op! fixes + ok op@

Not all commits will share the same author timestamp. This test would fail when run at the wrong time of day as found out by op@'s regress runner. ok op@

"sed -i" is fundamentally unportable. GNU and OpenBSD sed(1) treat the extension for the backup file as an optional argument and use "sed -i" for no backup file. FreeBSD sed(1) treats the extension as an obligatory argument and uses "sed -i ''" for no backup file. There is no single syntax that works for both. ok stsp op

Check if date(1) supports -r and fallback to gdate if that fails, via a shell-wrapper. From Christian "naddy" Weisgerber.

The fix for CVE-2022-39253 in Git made our regression tests fail since creating submodules from local clones is no longer allowed by default. Add an override to our invocations of "git submodule add", the same which was added to Git's regression test suite as part of their fix. This CVE doesn't otherwise affect us. We do not implement submodules. Our use of them in regression tests exists only to ensure that Got does not freak out when it sees one. Precisely because automated support for nested repositories and/or working copies (as in Git Submodules, or Subversion Externals, etc.) have been an endless source of security problems in other systems. sudden test failures pointed out by naddy@

This brings the rest of the regression test scripts in line with patch.sh.

This patch fixes test failures related the date(1) utility. In the long term we could add a wrapper function to detect valid options for date(1) and use the variant which works on the current OS. For now, this makes some tests pass and shows us where the problems are. OK thomas.adam

Always diff against latest version of file. This is much easier since there is no need to keep track of lines shifting around.
