Well, in PmWiki's case, historic tradition really was only a part
of the basis for the decision.  I could've eliminated the
whitespace=>preformatted rule in 2.0, but I decided that leading
whitespace really ought to mean *something*, and the only logical 
candidates were preformatted text and indented blocks.  
(And in 2.1 leading whitespace is able to serve both purposes
reasonably well!)

Hmm, there's not currently an easy way to do this (and leave
the other ws-indent rule intact), I'll have to see about
adding it.

Actually, in re-examining the code it looks as though the
Markup() rule I gave above for eliminating the leading space
also fails.  I'll have to fix that as well.  :-|
