Subject: g.region -a: different number of rows if using 'res' or 'nsres' and 'ewres' - though res=nsres=ewres=10!
Although the n,s,e,w are equal in both cases, and that res=nsres=ewres=10, the
number of rows in the resulting regions are different:
$ g.region n=5679000 s=5678670 w=599240 e=599880 res=10 -ag
n=5679000
s=5678670
w=599240
e=599880
nsres=10
ewres=10
rows=33 < !!!
cols=64
$ g.region n=5679000 s=5678670 w=599240 e=599880 nsres=10 ewres=10 -ag
n=5679000
s=5678660
w=599240
e=599880
nsres=10
ewres=10
rows=34 < !!!
cols=64
Please please please fix it before 6.2 release.

I've changed it in CVS.
Previously, ewres=/nsres= rounded to an even multiple of the
resolution, whereas res= simply rounded to a multiple.
