I could not apply it. If I copy-paste it out of the email, patch rejects it:

$ patch -p1 < vc-hg.patch
patching file vc-hg.el
Hunk #1 FAILED at 209.
1 out of 1 hunk FAILED -- saving rejects to file vc-hg.el.rej

When I try to apply it from Emacs, it asks me first if I want to fix
word-wrap damage, but after I say yes, it fails anyway... Sorry but
I'm not sure what is wrong.

You are right.

This is because you use "\"{rev}\"" as the template instead of
"{rev}".    I used "{rev}" and I get just the revision e.g. 290.
