[Dev-luatex] string.explode()

[Reinhard Kotucha]

Hi Taco,
though luatex isn't frozen yet, I think that many people are using it
already and drastic changes are not desirable.

There is one thing which could probably be improved without breaking
existing scripts, as far as I can see:

  string.explode(foo, ' +')  

expects that ' ' is a space token (ASCII 0x20).  Is it possible to
change string.explode() so that ' ' can be either a space token (ASCII
0x20) or a tabulator (ASCII 0x09) without breaking existing scripts?

Regards,
  Reinhard

Microsoft isn't the answer. Microsoft is the question, and the answer is NO.
