GP5: Three small bugs (in dusty corners)

[Philipp K. J. <ja...@ie...>]

I seem to have observed three minor bugs in gp5:


1) Filledcurve above/below

My understanding is that 
	plot sin(x) w filledc above y1=0
should fill only the area between y=0 and 
the sine curve. What I observe is that it
does not fill at all. With
	plot sin(x) w filledc below y1=0
gnuplot fills both above and below.

The plot is sensitive to the value supplied,
but above/below do not seem to be interpreted
properly.


2) Enhanced text, key, and cairo

	set key title "{/:Bold Hello}"
	plot sin(x) t "World"

I'd expect the title of the key to be bold,
but the title entry for the curve to be 
normal weight. That's also what it does in
wxt, but for any of the cairo terminals, all
key entries are bold.


3) set xmtics, save, load

(I agree, a truly dusty corner!)

	set xmtics
	plot "data" u 1:2 w l
	save "foobar.gp"
	load "foobar.gp"

This produces an error:

	set xmtics norangelimit
	unexpected or unrecognized token


No biggy all three, but I'd thought I'd point them 
out. Maybe worth a remark in the release notes.
