Subject: r.mapcalc seems to treat [0,1] like [0,2]

Platform: GNU/Linux/i386
grass obtained from: Mirror of Trento site
grass binary for platform: Compiled from Sources
GRASS Version: 5.0.0

If I do the following:

r.null grown null=0
r.mapcalc "grown=if(grown[0,0], grown[0,0], if(grown[0,1], grown[0,1]))"

r.mapcalc seems to treat [0,1] like [0,2] ..
(I'm trying to make a single-pixel wide line a two-pixel wide line)
