revision.c: the "log" family, except for "show", takes committish

Browse Source 
Add a field to setup_revision_opt structure and allow these callers
to tell the setup_revisions command parsing machinery that short SHA1
it encounters are meant to name committish.

This step does not go all the way to connect the setup_revisions()
to sha1_name.c yet.
