replace "(cd path && git cmd)" with "git -C path cmd" This matches the existing use of "got -r path cmd" and "git_commit path args".

regress: nix 'set -A' kshism from tests 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@

got: enable more commands to accept commit keywords 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@

fix regression test failures with Git 3.30.5 / 2.38.1 or later installed 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@
