help: provide a more helpful message when no keyword are matched

Before this changeset, when no topic were matching the provided keyword ( in
command such as `hg help --keyword babar`) the output was empty. This is
confusing and unhelpful for new users seeking assistance in the help.

We now display:

  $ hg help --keyword babar
  abort: no matches
  (try "hg help" for a list of topics)

This send users in a new direction where they may find what they are looking for.

#if test-repo pyflakes

  $ cd "`dirname "$TESTDIR"`"

run pyflakes on all tracked files ending in .py or without a file ending
(skipping binary file random-seed)
