It seems we would loose coverage with this patch, so it should be
dropped.

Yeah. I think we should add a comment to the travis.yml to avoid
future confusion. I'll do it unless you beat me to it with a re-roll.

Rather, it should be commented close to where is locale is used in
tests, and possibly in t/README, I would think.  Those who want to
use t/*, not necessarily using Travis, would benefit from the hint,
"installing icelandic locale may give you better test coverage", or
something like that.
