Converting TextMate Language Bundle gives funky syntax highlighting

[ernestum]

I just tried to convert the gnuplot bundle for TextMate to atom, because syntax highlighting for gnuplot is still missing. The conversion works without errors, and atom also shows me, that it thinks it is opening a gnuplot file when I open one (in the bottom right corner) but the syntax highlighting is either nonexisting or just weird (see
). I know that is not how it should look because of this screencast where the bundle is used in TextMate (see http://vimeo.com/2181877).
Steps to reproduce:
First

apm init --package ~/.atom/packages/language-gnuplot --convert https://github.com/mattfoster/gnuplot-tmbundle

Then open any gnuplot file.

Running under Debian Linux with Atom 0.123.0

So I looked into this and I believe this is because the grammar has a malformed pattern: https://github.com/mattfoster/gnuplot-tmbundle/blob/1b204c2728e65f027600ed2f7dd21559a0703a92/Syntaxes/gnuplot.tmLanguage#L181

The line contains |) which makes a zero width match and so the parser never advances.

I've forked this bundle and fixed it here: kevinsawicki/gnuplot-tmbundle@1942cc3

If you run apm init using my fork:

apm init --package ~/.atom/packages/language-gnuplot --convert https://github.com/kevinsawicki/gnuplot-tmbundle

it should highlight correctly now:
