Hi,

\setuphead seems to be broken for me in recent context (following
upgrade of a ~year-old system).

Problem happens when use the command= key.

An example from the wiki fails, as does my own code.

mtx-context     | ConTeXt Process Management 0.60
mtx-context     |
mtx-context     | main context file: /opt/context/tex/texmf-context/tex/context/base/context.mkiv
mtx-context     | current version: 2012.09.10 00:57

\setupexternalfigures[location=default] % needed only for the wiki to the find the figure

\useexternalfigure[section-1][cow][width=5cm,height=1cm]
\useexternalfigure[section-2][mill.png][width=5cm,height=1cm]

\setuphead
   [section]
   [command=\MySectionCommand]
\setuphead
   [subsection]
   [command=]

\def\MySectionCommand#1#2%
   {\externalfigure[section-\currentheadnumber]}

\starttext

\section{One}
\subsection{First subsection of Section One}
\section{Two}

\stoptext

ERROR: Argument of \MySectionCommand has an extra }.

--- HELP ---
From the .log file...

I've run across a `}' that doesn't seem to match anything.
For example, `\def\a#1{...}' and `\a}' would produce
this error. If you simply proceed now, the `\par' that
I've just inserted will cause me to report a runaway
argument that might be the root of the problem. But if
your `}' was spurious, just type `2' and it will go away.
