Hi,

ps - general IPY interest of what happens in a "corner" case:
pic of output v.proj'd into EPSG#3033 attached (LCC). blue crosses
indicate +lat_1 and +lat_2 for the projection, centered on the Lambert
Glacier (no relation) and Amery Ice Shelf. d.grid -g goes a bit nuts
once you zoom out so far from the projection's region of purpose; v.proj
held up pretty well except for directly across from +lon_0=70 (middle
bottom). 180 lon break is there but easily cleaned with v.clean tool=rmsa
PROJ4 values for EPSG Polar Stereographic epsg codes don't exist.
