#1628 iec80k prefixes for ticslabels

[Anonymous]

The ticslabel generation with format "%B"

set format x "%.b %BByte"
set logsc x
plot [1:1e5] x

breaks for values between 1 and 2^10, because the code after util.c:878 has no provision for "power" = 0.

Attached patch add a test for that and just puts nothing in the output string.

That was me, and I forgot to give diff -u again, sorry.

A similar change is in CVS now. Thanks for spotting this.
