shortest possible match | non greedy match about nex HOT 3 CLOSED

This behaviour has been inherited from Flex: http://flex.sourceforge.net/manual/Why-doesn_0027t-flex-have-non_002dgreedy-operators-like-perl-does_003f.html. In short, they recommend moving the logic from the lexer to the parser, or using start conditions (which nex does not support yet).

However, I'm willing to add non-greedy operators to nex if I can find the time. Stay tuned!

Thanks for your help 👍 . I moved said logic to goyacc, but the resulting code is not the prettiest. For my use case, a lot of code duplication arose because I'm only interested in the tokens inside PHP code.

I look forward to your changes :)

(Since nex seems sort of unmaintained, I've resorted to looking at closed issues for hints! Let's all drop any learnings that we get to, somewhere like here!)
