Details:

When invoking datetick, and if datetick needs to recompute the X-axis tick,
grid & label positions, it is expected that the previous ticks, vertical grid
lines and labels are removed.
When using gnuplot this doesn't happen (fltk works correctly).

Steps to reproduce (use attached data in file series.mat, as those data
require datetick to recompute the X-ticks):

load series.mat
graphics_toolkit gnuplot
plot (series(:, 1), series(:, 2))
grid
datetick

and you'll get the result in the attached picture.

This works correctly with gnuplot in octave-3.6.4 for MinGW.

If it helps: the oldest 3.7.x I have installed is Michael's 3.7.2+ MSVC
snapshot binary, and that has this bug. So it must have sneaked in before Feb
22, 2013 (creation date of octave-3.7.2+.exe)
