[PATCH v3 0/3] permit -h/--help-all in more scenarios

Changes from v2:
- Rebase on unpublished ua/t1517… v5 (https://lore.kernel.org/git/20250803020744.1037392-1-usmanakinyemi202@gmail.com/)
  which is rebased on master
- Changed fixup to account for instaweb Perl dependency

Changes from v1:
- tweak refactor commit message to indicate no behavior is changed;
- use #define'd constants instead of an enum for internal flags;
- drop controversial [4/4]

QQ: Is there a better way to add --cc's to format-patch than grabbing
the right folks off threads from lore.kernel.org/git? (I could also grab
them out of my mail client.) I assume this is where using tools like b4
starts to really shine? To be clear: I mean CC's _in addition to_ the
use of

    sendemail.ccCmd = perl contrib/contacts/git-contacts

to keep folks that participated in prior rounds of discussion abreast of the next version.

-------- Original --------

This series depends on ua/t1517-short-help-tests with some fixes, which show up in the first patch. Start a new topic from the (unpublished) v5 of that branch:

    git switch -c topic origin/master
    git am ua/t1517-short-help-tests-v5.mbox

Then apply this series.

This series enables --help-all outside of repository contexts, and allows -h with other arguments (without breaking existing ls-remote/grep usage).

It consists of preparatory steps (fixes for a dependency branch; refactoring to make an internal helper's arguments clearer) followed by the main commits.
