Awesome and thanks.

If this was requested previously, would there be a trac issue?

This is something that I'm concerned about. If there's one path format,
an application may have to do something 'interesting' if it has two
paths with different formats. I'm all ears on how to fix this scenario:

I have an application that is standalone that can run in /home, that
uses the compact path. But it's also able to be installed system wide,
which means it'd be best for it to use the /usr/share/locale thing. How

Of course, a single path format would solve a lot of problems I've
mentioned so I'm happy to do that. I'm just a little concerned about
that scenario.

Ah, I'm new to ABIs and whatnot so I wasn't really paying attention.
I'll get that done, but I'd also like to know about my concerns with the
first issue, as this implies a single path.
