Re: How to view an old revision?

I was actually reviewing the documentation of git-rev-parse and
noticed that it talks about naming objects in the section called
"SPECIFYING REVISIONS".  The title implies that it is about
committish (because we think of "revisions" as something that is
used in walking commit ancestry chains), but it actually talks
about naming objects of any type.

There's no way I would have known to look in git-rev-parse.  My
git-rev-parse man page doesn't mention the colon syntax, but now I see
that part in git's gitweb; my man page must be too old.  Either (1) or
(2) would have been enough for me to figure out that the colon syntax
would do what I wanted, but to grab the attention of the less
persistent user, it would be good to mention the particular case of
"git-cat-file <commit-ish>:<file>" in the git-cat-file man page.
