I would throw this not into the incomplete scriptability category but into
the "user does not know how to use his pager" category.  With "/^commit .*"
you can not only advance to the next commit with "/<RET>", you can go back
to the previous one with "?<RET>", and keep going in the same direction
with "n".

If anything that shouldn't be an option to "log", but to "rev-list", as
you are aiming for scriptability.  But

    git rev-list --for-each='cmd that takes commit as its argument'

wouldn't be much of an improvement over "git rev-list | xargs -n1 'cmd'"
pipeline from the _scriptability_ point of view.

So no.
