Makefile target "uninstall" missing

[Dr Rainer Woitok]

Greetings,

no, I don't want to get rid of Mercurial.  Honestly :-)

But recently I had the need to cleanly uninstall the currently installed
Mercurial version in order to check out, build and install another Merc-
urial version.   I ended up using "gawk"  to create "rm" statements from
lines containing "/usr/local/" in the saved (!) install log.  This cert-
ainly should not be the way to do it, should it?

Sincerely,
  Rainer
