[Proj] Costa Rica Norte in nad/world definition...

The PROJ.4 file nad/world contains a definition for the "Costa Rica Norte"
system (costa-n) that may have a typo.

The false northing is listed in this file (in current SVN) with

but I believe that it's really supposed to be y_0=271820.522 instead.

We received some data for this coordinate system from a customer and it uses
this definition.  With the "corrected" numbers, the customer's locations in
geographic and projected coordinates match when converted using "proj."

However, I can't find another source for it on the web anywhere to confirm.

Does someone have a way to check this out?
