Ok, I settled for %g[dDs] for now to save on letters.  I'm saving the
syntax question for a later series while we discuss this one ;-)

I think going for %(...) wouldn't be too bad since we already have
that in for-each-ref, and it can be backwards compatible.  So we would
have different sets of short and long specifiers, e.g.

  %ae = %(authoremail)
  %aE = %(authoremail:mailmap)

We can then pass arguments via some yet-to-be decided syntax, say,
%(body:indent(10)).

Other changes in this version include:

* I followed your struct suggestion, which is the new 1/5.

* Since the shortening can be handled by %gd, the old 5/5 (change from
  refs/stash to only stash) is no longer needed.

* I fixed the warning that Junio found (and finally found the right
  combination of -W flags, though I cannot compile with -Werror myself
  because of *other* warnings...)

I also added tests and docs to the main patch (now 3/5).
