I can apply the patch to CVS over the weekend. But I will be travelling
for the next 3 weeks, and will not be able to deal with any fallout or breakage.
Unfortunately, neither my patch nor Daniel's will apply directly against 4.2.
Both are large enough changes that I would worry about seriously breaking
something in 4.2 if there is a rush to back-port the new code.

I think I will have to release a quick 4.2.2 anyhow, because the lack of
axis labels is indeed serious. But that is a two-line fix. To replace
the old zooming code and then back-port the "refresh" implementation
is way more than I could do quickly. Let's get it into CVS so that it
sees some testing over the next few months. At that point we can decide
whether it's solid enough and worth another 4.2.x release.
At least a few of the Octave users should be willing to build gnuplot
from cvs, and that will hopefully provide more immediate testing than
new features often get.
Or if you take the lead in backporting to 4.2 and thorough testing,
maybe it could be done more quickly?
