setup: add hgext.lfs to list of Python packages
This is needed for lfs to get installed. Probably could stand to go
into an earlier patch, but I just want to get this stuff pushed.
#require test-repo jshint hg10
$ . "$TESTDIR/helpers-testrepo.sh"
run jshint on all tracked files ending in .js except vendored dependencies
$ cd "`dirname "$TESTDIR"`"
$ testrepohg locate 'set:**.js' \
> -X mercurial/templates/static/excanvas.js \
> 2>/dev/null \
> | xargs jshint
