Test help hooks

  > 
  > def rewrite(topic, doc):
  >     return doc + '\nhelphook1\n'
  > 
  > def extsetup(ui):
  >     help.addtopichook('revsets', rewrite)
  > EOF
  $ cat > helphook2.py <<EOF
  > from mercurial import help
  > 
  > def rewrite(topic, doc):
  >     return doc + '\nhelphook2\n'
  > 
  > def extsetup(ui):
  >     help.addtopichook('revsets', rewrite)
  > EOF
  $ echo '[extensions]' >> $HGRCPATH
  $ echo "helphook1 = `pwd`/helphook1.py" >> $HGRCPATH
  $ echo "helphook2 = `pwd`/helphook2.py" >> $HGRCPATH
  $ hg help revsets | grep helphook
      helphook1
