One thing I wondered about this in the original version was if the
returned value should be localized.  In the context of the original,
the --porcelain mode refused to give this information in its output,
so it was OK to always localize the returned value to satisify the
other caller who wanted end-user-facing output.

But as a more general helper, I am not sure if this is the most
useful way to implement it.  Shouldn't the function rather return
the machine-readable tokens and allow callers to localize it as
needed with its own _() around the returned value?  I dunno.
