templatekw: add compatlist() as a replacement for showlist()
Just like compatdict(), this is mostly a copy of showlist(). showchildren()
is ported to the new API as an example.
#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' \
> 2>/dev/null \
> | xargs jshint
