userdiff: add Octave

Octave pattern is almost the same as matlab, except
that '%%%' and '##' can also be used to begin code sections,
in addition to '%%' that is understood by both. Octave
pattern is merged into Matlab pattern. Test cases for
the hunk header patterns of matlab and octave under
t/t4018 are added.
