That can work out, though unless I'm missing something, I need to move
to the org-mode repository, ask "git branch --contains", and parse the
output.  Possible, but somewhat involved.

(TIL: git-describe's "{tag}-{nbcommits}-g{hash}" is actually a valid
revision format that other Git commands understand.)


For the sake of completeness, I've tried visiting org.el and evaluating

    (package-desc-version (package-buffer-info))

but package-buffer-info ends up calling (version-to-list "9.4-dev"),
which chokes on "-dev".  FWIW, that can be worked around with:

    (add-to-list 'version-regexp-alist (cons "^-dev$" -1))

Right, that's my conclusion as well :)
