octave: libinterp/corefcn/xpow.cc annotate

annotate libinterp/corefcn/xpow.cc @ 28636:a3db48e66ef8

use Range::increment instead of Range::inc This change is a step toward replacing the current Range class with the new range template class. * Range.h (Range::increment): New function. Change all uses of Range::inc to use Range::increment instead.
