I guess there are two cases.  You are pulling from a source repo, and
you just want the latest head.  Or you want a specific revision.  I
would suggest the addition of a "REV=foobar".  In it's absence, just
pull on every run, to get the latest head.  With that variable, treat
git like a tarball that can be cached, pull once, keep it cached for
ever more.

Under the "just pull the latest" scenario, the sha1 is meaningless, put
under the "pull a specific revision" scenario, the sha1 should be for
the entire directory pulled.  Though in the case of git, the revision
"number" IS part or all of an sha1 for the directory.  So perhaps for
git REV would equal SHA1 anyway, but not all source code repo software
does that.  So if you want something more generic, keep REV and SHA1
different beasts.

Just my two cents before I actually wake up properly.
