Subject: lcc projection in g.setproj

g.setproj (relevant code also in src/libes/gis/geo_init.c) does not
prompt correctly for the standard parallels in the Lambert Conformal 
Conic (lcc) projection.
Should be EITHER one central parallel (lat_1) OR
first and second parallels (lat_0 and lat_2)

Markus asked me to fix this but I don't think it's trivial and it may
be better to wait until g.setproj is re-written. Prompting for the 
necessary parameters for each projection is really something PROJ.4 should
do but as far as I can see it doesn't. The parameters should however
be in a data file and not hardcoded into src/libes/gis/geo_init.c and
src/include/geo.h I think (although this was probably a nice tidy 
solution back in the early 90s when GRASS only supported the few 
projections that are used in the State Plane system).

Paul,

maybe the current partial rewrite of g.setproj fixes this one?
