Seems `\definedescription' do not work

Seems `\definedescription' do not work

[Vladimir Lomov]

Hello,

I borrow this example from wiki:
<example file="ex2.tex">
%\setupbodyfont[computer-modern-unicode,12pt]

\definedescription
  [Desc]
  [location=top,hang=20,
   headstyle={\bf\color[blue]},
   command=\hskip-1cm,margin=1cm]

\starttext
\startDesc{Tufte}
\input tufte
\stopDesc
\stoptext
</example>

but context can't compile it:
<terminal output>

The time was the 19th of May, 1780.  The place was Hartford, Connecticut.
The day has gone down in New England history as a terrible foretaste of
Judgement Day.  For at noon the skies turned from blue to grey and by
mid-afternoon had blackened over so densely that, in that religious age,
men fell on their knees and begged a final blessing before the end came.
The Connecticut House of Representatives was in session.  And, as some of
the men fell down and others clamored for an immediate adjournment, the
Speaker of the House, one Col. Davenport, came to his feet.  He silenced
them and said these words: "The day of judgment is either approaching or
it is not.  If it is not, there is no cause for adjournment.  If it is, I
choose to be found doing my duty.  I wish therefore that candles may be
brought."

The problem is \color which expects a argument for the text to be colored (e.g. \color[blue]{…}) which is never the case when you put it in a style key but you can use the color key to set the value.

\definedescription
 [description]
 [alternative=top,
  headstyle=bold,
  headcolor=blue,
  headcommand={\offset[x=-1cm]},
  margin=1cm]

\starttext

\input tufte

\startdescription{Tufte}
\input tufte
\stopdescription

\stoptext

Yes, it is true, I saw some topics about that on ML but forgot (this
example from my old code).

Thanks, this is much "cleaner" solution. (Again, I already saw message
about change from `location=' to `alternative='.)
