BUG
r.bilinear write 0 instead of NULL:

GRASS:~ > r.info -r elev.bilin
min=0.000000
max=1432.306152

GRASS:~ > r.null elev.bilin setnull=0
Writing new data for [elev.bilin]... 100%

GRASS:~ > r.info -r elev.bilin
min=1136.674438
max=1432.306152

This happens at the west/north result map borders where 0 instead of NULL
is written.

is written.

It should only be East/West. The North/South check writes NULLs.

I've committed a fix; this should probably go into 5.0.3.
