[GRASS5] bug in d.what.rast

[Roger Miller]

Folks,

d.what.rast in GRASS pre2 is broken.  The -c flag produces incorrect results. 
The problem was introduced somewhere between beta11 and pre2.  The beta11 
version works.  I did track down exactly what the problem was, and it looks 
like it's still there in the current version.

Briefly, the definition of the show_utm function was modified to pass the 
name of the mapset as an argument.  That causes show_utm to skip the call to 
G_get_cellhd that fills the cellhd structure; the column and row numbers are 
then calculated on the basis of  cellhd.north = cellhd.west = 0.

The easiest solution is just to revert the code to the earlier version.
