[GRASS-dev] r.info cleanups

[Hamish]

Hi,

In CVS I have done some r.info cleanups.

* "print & exit" foo=bar command line options can now be combined.
G63> r.info roads -rt
min=1
max=5
datatype=CELL

* "Data Source:" is only printed if it exists (saves 4 lines in the
fancy output). If no "Comments:" the full info now fits in 80x25.

* Projection only prints out "(zone %d)" if proj is UTM. Note that the
projection and zone info comes from the current Location settings, not
.proj and .zone in the map's Cell_head structure! (if they don't match
you should get an error when you try to open the map)
