The actual CVS version of this file, from almost the beginning of the 
public repository, to the 4.0 branch point and beyond, all the way to 
almost the 4.2 branch point, was 1.1.1.2.  All branches before the 4.2 
one originate at revision 1.1.1.2, getting branch-point numbers like 
1.1.1.2.0.{n}.

As the numbering indicates ('*.1.n', instead of '*.2.n' of ordinary 
branches), this revision is from one of those pesky CVS "vendor" 
pseudo-branches which the conversion tools apparently shy away from as a 
vampire from garlic.  Apparently Lars Hecking used "cvs import" to track 
early development from his own machine(s) into the new public repository 
at SF.net.  That vendor branch itself is called "GNUPLOT_BETA", and all 
the BETA_34* tags are on this branch.

About 2 dozen files in our project (primarily demo/*.dat) are apparently 
_still_ on that branch, because they were ne7ver changed since the 
initial check-in.
