help: test if "hg help TOPIC" reference is valid
It's quite easy to make a reference invalid by mistake.

+Check if ":hg:`help TOPIC`" is valid:
+(use "xargs -n1 -t" to see which help commands are executed)
+
+ $ hg files 'glob:{hgext,mercurial}/**/*.py' \
+ > | xargs python "$TESTTMP/scanhelptopics.py" \
+ > | xargs -n1 hg help > /dev/null
