patch for rrdtool-1.2.19

[Carter Bullard]

Gentle people,
With regard to ragraph() and the rrdtool /J option not being supported
in the latest rrd-tool distribution, here is the patch that can be  
applied to
the latest,  rrdtool-1.2.19.  Until I can get a dialogue going with the
rrd-developers, I'll provide these patches in the ragraph subdirectory
(once we're happy that they work).

This modification allows us to get alignment of legend entries,  
without it
the legend can shift by a single character, if there are multiple  
lines of entries,
which doesn't look very good.
