set xtics 0 rejected on the current cvs (ChangeLog 2015-07-11)

[Tatsuro M. <tma...@ya...>]

gnuplot>  set xtics 0

         ^
         increment must be positive

So that demo imageNaN.dem fails:
gnuplot> load 'imageNaN.dem'

gnuplot> set xtics 0
         ^
         "imageNaN.dem", line 23: increment must be positive



Perhaps the change

    * src/set.c (load_tic_series): Incorrect nesting of brackets caused
    "set xtics 0" to be accepted rather than rejected.  This could lead
    to various bad outcomes (as found by fuzz-testing).
does not work for me.


At the moment, I have built the current only on Ubuntu 14.04 LTS amd64.
I have preparing built on Cygwin and native windows.
