Only because your requirements are unsound. It's not possible to
specify a revision compactly, let alone uniquely, in a "preorder of
patches" VCS like Darcs. (Unlike the example below, it's not always
going to be the case that you can refer to a particular patch as a
summary of the situation.) So broad portability across VCSes is out.
And it's not really necessary: at any given time there's only going to
be one canonical VCS for a project, so references can (and IMO should)
use that VCS's identifier.
Constructing a reference that is reasonably accurate and meaningful to
humans is also very difficult (at least). Even restricting yourself
to a single VCS like git, there may be insufficient metadata to remove
ambiguity. On the other hand, although for academics "Raymond [1997]"
is a form that makes a lot of sense, in referencing commits in a VCS
it's nowhere near as useful. Human memory for commit content has a
halflife of about 2 weeks -- and that's assuming you were both
following emacs-devel and emacs-commits at the time. Then you go and
look for it -- guess what, grepping the ChangeLog doesn't work if (as
in many projects, and I understand that many hope Emacs will
eventually be one of them) you don't have ChangeLogs.
I really don't see what's wrong with

It was a funny-once, Man.
Or whatever formatting you want, as long as the SHA1 ref is easily
parsable out of the text.
