Engines are started; first car is out the gate

[Ethan A M. <merritt@u.washington.edu>]

As of this evening I have merged into CVS the three large
patches I had more or less ready to go [*].  

filledcurves	(no configuration options)
    fill above/below bounding curve
    fill between 2 curves
    apply fill styles to filledcurves
    allow term->filled_polygon() even without PM3D support
    demo:  fillbetween.dem

datastrings	(defaults to --enable-datastrings)
    plot with labels
    splot with labels
    using xticlabels(<col>) title <col>
    demo: datastrings.dem

histograms	(defaults to --disable-histograms)
    set style data histograms <opts>
    with histograms {clustered|rowstacked|columnstacked}
    set key invert
    demo: histograms.dem histograms2.dem


I have a few other minor patches that need to be revisited
post-ANSIfication, but they are not likely to be road obstacles
to others.  I will feed them in as I get a chance to check them.

I also have some largish patches corresponding to implementations
of several different flavors of user-accessible string variables.
These have been discussed off and on over the last year or so,
but I never sensed a real consensus as to which approach was
best. I will not merge any of these into CVS without further discussion
on the mailing list.  As I find time I will update them and put them
on SourceForge for people to look at again.  


	So -- who is next out of the gate?  


[*] They were quite ready a week ago, but the ANSIfication of the
source tree made them rather less so.  I'm still tracking down a
few minor glitches introduced into the code for columnstacked
histograms.  I also discovered and fixed a number of problems
arising if you try to build with --disable-pm3d.  Some of these should
probably be fixed in the 4.0 tree as well.
