White space balance has changed

[Daniel J S. <dan...@ie...>]

I've been stepping through the demos, and my general observation from 
what I remember is that there is now much less white space around plots. 
  The behavior is the same in two different terminals (x11 and qt). 
I've gone back to about -D2016-05-25 in the repository to see if this is 
a current inadvertent change.  It's the same as current development version.

Has anyone else noticed this?  Perhaps it was intentional, and in some 
sense I don't mind it because it makes the plots use more of the 
available window screen.  I mean, typically when I create a plot for a 
publication I will reduce the whitespace to minimal because word 
processors can always add it back in.  That can be done changing the 
margins or post-gnuplot with some cropping tool specific to, say, eps or 
something.

However, as far as the demos, the plots don't feel as though they have a 
good white space balance for several plots.  Here are some notable ones:

fillcrvs.dem (7) world.dat plotted with filledcurves
multiplt.dem (1)
[The above two illustrate how plot are is slightly skewed to the left]
heatmaps.dem (1) (2) (3) (4)
piecewise.dem (1) Piecewise function sampling
matrix_index.dem (1) Data file contains labeled ascii matrices
