Check if ":hg:`help TOPIC`" is valid:
(use "xargs -n1 -t" to see which help commands are executed)

  $ NPROC=`hg debugpython -- -c 'import multiprocessing; print(str(multiprocessing.cpu_count()))'`
  $ testrepohg files 'glob:edenscm/**/*.py' \

Remove subversion from the list; it does not work on macOS and casuses this test
to print errors.
  $ grep -v subversion $TESTTMP/topics > $TESTTMP/topics_filtered
  $ cat $TESTTMP/topics_filtered | xargs -n1 -P $NPROC hg --cwd / help >/dev/null
