Subject: zoom broken in LL locations beyond poles

Platform: Mac OSX
grass obtained from: Trento Italy site
grass binary for platform: Compiled from Sources
GRASS Version: 5.7cvs

When zooming/panning in lat-long locations, the window won't pan beyond the poles (+-90 deg).

When using d.zoom it snaps the n/s extent to +-90 deg.  When using v.digit zoom/pan tools, it 
says:

WARNING: G_set_window(): Illegal latitude for South/North

and does not zoom or pan at all.

Zoom/pan beyond 180 deg E/W works.  In d.zoom it gives a polite warning and does zoom/pan 
(with wrapping around to the other side).  Same with v.digit, just no warning.

Zoom/pan in projected locations works (with the same warnings in d.zoom).

This makes it nearly impossible to edit vectors at or near the poles.  Display works since it snaps to 
+-90 deg, but it would be nice to have a margin.
