[GRASS5] [bug #3876] (grass) g.proj: proj4= fails, wkt= works partialy

[Maciek Sieczka via RT]

BTW this issue with creating projection from EPSG code, which is OK now, I
re-tested all the g.proj stuff which I complained about in my original bug
report. Looks all works fine, however I have one question about differences in
units names in case when wkt or proj4 option is used.

# When I override current projection using a wkt file, the projection units
# are in small letters:

$ g.proj -c wkt=puwg1965_I.prj
$ g.proj -p

# But when I specify the same projection in proj4 syntax unit and units names

$ g.proj -p

-PROJ_UNITS------------------------------------------------

Why the difference? Any problems possible due to this? Even if not, could the
naming convention be unified?
