Just to be clear on something that was not mentioned on this patch yet, this is a work on top of the publishd function from the miscellaneous package:

  http://hg.code.sf.net/p/octave/miscellaneous/file/ae5cf73a03e1/inst/publish.m

It was also listed on the tasks #12153 "Incorporate Octave-Forge core functions into Octave"

  https://savannah.gnu.org/task/?12153

What should be done about the miscellaneous package?  How incompatible is this new version?  Is it worth keep the older one under a different name?

Some possible approaches:

• remove publish from miscellaneous
• remove publish from miscellaneous and bump its dependency to Octave 4.2
• have installation of miscellaneous only include the old version of publish() in Octave versions that miss the function
• duplicate the new implementation of publish() to the miscellaneous package and install it only in Octave versions that miss the function
• rename the old version of publish in the miscellaneous package, and deprecate it (maybe mixed with one of the options above)

I'm leaning towards the first solution since the package is not really maintained and I don't remember anyone mentioning using that function from that package.

Awesome!  This feature is very useful in teaching so I would think it should be high priority.

Will will try to test when I get a chance.
