Comment (by hamish):

 Center coord via another method for comparison:

 {{{
 g.region -c
 center easting:  -164500.000000
 center northing: -2107500.000000

 echo "-164500 -2107500" | m.proj -o --quiet
 132d26'33.612"E 18d18'35.426"S 0.000
 }}}


 which doesn't match either -b or -l's version, but looks about right if
 you plot it over 'd.grid -g 10':
 {{{
 # d.mark from wiki addons
 d.mark -m at="-164500,-2107500"
 }}}

 compare:
 {{{
 g.region -l
 center longitude:  42:35:00.190847E + 180 = +137.4166137
 center latitude:   11:51:25.545225S

 echo "137.4166137 11d51'25.545225\"S" | m.proj -i --quiet
 380455.32       -1390800.80 0.00
 d.mark -m at="380455.32,-1390800.80" fcolor=red
 ## (off a way to the NE)
 }}}

 {{{
 g.region -b
 center [lon]: 118:53:40.840749E
 center [lat]: 12:21:00.985478S

 echo "118d53'40.840749\"E 12d21'00.985478\"S" | m.proj -i --quiet
 -1671525.94     -1541908.71 0.00
 d.mark -m at="-1671525.94,-1541908.71" fcolor=blue
 ## (off even further away to the NW)
 }}}
