Comments not visible in po files for one string; fixed line order in templates file.

Several translators have translated values, which need to be left untranslated
(question for typical usage of filesystems). I have fixed the translations
already in the previous upload.
There was already a comment in the templates file explaining this fact, but that
comment didn't make it to the po files, because of wrong order in the templates
file. This is fixed with this commit.
