I don't see any reason to change our script files, like sombrero, to match
Matlab.

But I don't object to having the plot %!demo blocks in Matlab format.  This
has already been done for the demo blocks in the plot directory
specifically to make use of the compare_plots routine.  line.m is a good
example in that the %!demo block uses single quotes, but the %!test block
uses double quotes because it is Octave-only.  If we are really bothered by
this we could recode the demo blocks using Octave conventions and then run
oct2mat on the demo blocks when generating the compare plots script.
