Shouldn't we default target_platform=None since grd_reader has a default, and we
use this externally (See the attempted grit roll here:
https://codereview.chromium.org/23658022/)?

We should default it to target_platform=None, correct. It looks like in practice
that's what happens since the command-line parsing defaults this to None if not
set, but would be nicer to default the parameter to None as well.

       filename, defines=defines, tags_to_ignore=set(['messages']),
