[GRASS5] r.rescale range question

[Markus Neteler]

Hi,

while looking at r.rescale I found

 r.rescale [-q] input=name [from=min,max] output=name [to=min,max]
   [title="phrase"]

[...] 
      to   The output data range
           default: 1,255

This range looks a bit unusual. Shouldn't it be 8bit = 0..255?
