One thing for the future, and one thing for the present.

 - Do some languages we would add to po/ hierarchy in the future
   possibly want to use these sequences as legitimate contents?

 - Do we need ls-files?  


For the latter, shouldn't the attribute-based pathspec work just
fine with "git grep"?  i.e.

    git grep -l -E -e $pattern -- ':(exclude,attr:binary)'
