Initial Comment:
Setting region to cover only the selected vector alligning to resolution fails. To reproduce:

#import line:
$ echo "L  2 1
 602473.66691719 5680962.45268225
 602448.70284465 5680961.09147704
1     1" | v.in.ascii -n form=standard out=line

# set the region somewhat bigger than the line:
$ g.region g.region n=5680965 s=5680959 w=602430 e=602493 res=1

#now try to set the region to cover the vector, alligning to resolution:
$ g.region vect=linia res=1 -a

#let's see what was the region set to:
n=5680963
s=5680960
w=602448
e=602474
nsres=1
ewres=1
rows=3
cols=26
cells=78

That's wrong. Rows should be 2, as south should be 5680961, not 5680960, because vector's south extent is at 5680961.09147704.

The bug is present only in 6.3 CVS! Can't reproduce it in current 6.2 CVS.
