Now yes:

i.fusion.hpf pan=$PAN msx=$(g.list raster pattern="$COLORPREFIX.?"
sep=comma) -c --o

# band 8
r.info -r wv2_17OCT08182034_M2AS_058891334010_01_P001.8
min=0
max=1605

r.info -r wv2_17OCT08182034_M2AS_058891334010_01_P001.8.hpf
min=-1163.98434592277
max=3879.99538075697

So, -c doesn't seem to have any effect here.
