Subject: suggested feature: someone mails me a blob, git please tell me what it is
Message-ID: <3c6c07c20702160823j316c52f4pe4cf5ca8a882e194@mail.gmail.com>

Here's a suggestion for a git feature, if git doesn't already have it.
 Since git generally doesn't use RCS-style keyword cookies (like
"$Id$"), it'd be nice to have some other way to identify an installed
file.  Perhaps you'd want to know exactly what rev a user is running,
for example.

It seems like it should be fairly easy, given a blob (the file), for
git to describe what it knows about it.  For example, it could provide
a list of commits that it's a part of, etc.  It'd be *really* nice if
only the output of the sha1sum command on the blob were needed.  (I
can't recall exactly how git's blob SHA1's are computed--maybe this
isn't feasible.)
