[PATCH] manual: Update LOCPATH documentation

[Florian Weimer <fweimer at redhat dot com>]

I noticed that the LOCPATH documentation had bitrotted and did not match 
the current defaults anymore.

It's also a bit odd that we go to great lengths *not* documenting the 
actual format of locale specifiers (mostly the 
language_TERRITORY.codeset@modifier structure), while this format is 
very much part of our public interface and described in the setlocale(3) 
manual page.  What's the current thinking on that?  Should we add this 
to the manual as well?

 The path used for finding locale data can be set using the

 Here is an example showing how you might use @code{setlocale} to
 temporarily switch to a new locale.
