If size 0 and -1 (not 1 as you seem to have read) are illegal (they

Same for the other arguments. I'll send a patchlet if noone did fix
that by next week.

-s 1 did work for me last time i looked.
In fact, back then only 1 worked, i got errors for bigger values i tried
(42,128,256,512,1k,2k,4k,16k,32k,64k,128k,42M etc).
