Updating generated lua help

[Mojca M. <moj...@gm...>]

Hello,

may I request updating lua help? (Else the system keeps complaining
about modified file.)

The option has been added by Ethan's commit:

2011-07-20  Peter Hedwig <pe...@af...>

  * term/lua/gnuplot-tikz.lua:  Point types 10 and 11 were upside down.
    Bug #3368877
  * fill paths now have a pensize > 0 to have slight overlap of tiles to
    avoid rendering artifacts
  * path building was broken and showed interrupted lines on certain plots
    e.g. plot '+' u 1:($1**2):($1**2) with lines pal lw 3 title '$x^2$'
  * a new terminal option (tightboundingbox|notightboundingbox) is added

but the corresponding generated files have not been updated.

Also: macports developers discovered that the TeX files like
gnuplot-lua-tikz.sty don't obey DESTDIR during installation. The weird
thing is that I'm not yet able to reproduce the problem outside of
macports (but it is consistent inside macports), so I'm not yet sure
how to provide a "minimal example" for that.

Thank you,
