I suggest everyone who tries this puts in those 'show xrange' between 
plots to see what actually happens.

There are two separate issues here.

1) plot [10:0] sin(x) may never change the state of the reverse option 
of 'set xrange'.  It doesn't change the range itself, so it should leave 
the reverse option alone, too.  But this in and of itself is relatively 
harmless.  This bug has been in the program since at least 4.2.3

2) The visible bug that the x axis is actually still reversed in the 
third plot appears to be newer.  It was introduced after 4.2.3, and is 
still  present in the current CVS head.
