extensions: drop dead code trying to exclude deprecated disabled commands
Here 'ext' is a tuple, which means ext.__doc__ describes about the Python
tuple type. Fixing this would break 'hg help glog', which currently shows
some nice explanation, so this patch just removes the dead code.
$ hg help glog
'glog' is provided by the following extension:
graphlog command to view revision graphs from a shell (DEPRECATED)
(use 'hg help extensions' for information on enabling extensions)
#require test-repo
$ . "$TESTDIR/helpers-testrepo.sh"
$ cat <<'EOF' > scanhelptopics.py

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