FreeLists / dokuwiki / [dokuwiki] Re: List syntax

[Adrian Sai-wah Tam <adrian@xxxxxxxx>]

Thanks Ferdinard, I follow your pointer and coded the attached plugin 
(supposed to be put on lib/plugins/mllist/syntax.php), which makes all 
the lines following a bullet with 3 or more leading spaces concatenated.
Everyone please enjoy.

Regards,
Adrian.
