`use-prompt-escapes' has nothing to do with normal `vcs_info' execution,
as documented it is *only* used by `vcs_info_lastmsg'.

You need to set the `check-for-changes' style. After that, it should
work.  I'm not sure if with the hg backend, it's also required to set
the `get-revision' style (Seth?).  If it is, that's missing from the
manual and should be fixed.

There is a file `Misc/vcs_info-examples', which is included with newer
versions of zsh. If contains a number of examples for `vcs_info' as its
name suggests.

There is also a blog entry by Seth (whom I've Cc:ed) which gives
pointers towards using `vcs_info' with mercurial. He extended the hg
backend a lot, so he knows what he's doing:
