Backwards compatibility problem?

[Giuseppe Bilotta]

Hi,

again, testing the new ConTeXt with "old" documents, I noticed
that

\definedescription[Desc]
                  [headstyle=italic,
                   before=,after=,
                   margin=2\parindent,
                   width=15em]

doesn't work in the new ConTeXt, while it worked in the old one
(the new one causes a "missing \endcsname" error).
