As there currently is no handling of warning or error messages at all,
the user has no sensible way to find out about them at the moment.
Reading parts of there messages (the whole wont fit in most cases) in
the place of the revision number in the status bar is no "solution"
worth keeping IMO.

Unfortunately, no.  This was my thirst idea, too...

I fully agree.  But until this is implemented I still think that my
simple patch provides an improvement over the current situation.  As
currently vc-hg stops working in a perfectly regular situation.
