Hi Rik,

The example isn't quite as minimal as it could be... Here is a
simplified version demonstrating the problem:

\setuplayout[backspace=4cm]

\define[2]\MarginHead{\inmargin{#1 #2}}

\setuphead[section][
alternative=text,
command=\MarginHead,
]

\defineitemgroup[itemz]
\setupitemgroup[itemz][each][joinedup]

\startbuffer[Item]
\startitemz
  \item Item
  \item Item
\stopitemz
\stopbuffer

\starttext
\section{No Whitespace}
No extra whitespace before items.
\getbuffer[Item]

\section{Extra Whitespace}
\getbuffer[Item]
Unexpected extra whitespace before items.
\stoptext

Here is one way to get rid of the extra white-space. I could not figure out a clean way of adding this signal to the setup.

\setuplayout[backspace=6cm, leftmargin=5.5cm]

\define[2]\MarginHead{\inmargin{#1 #2}}

\setuphead[section]
 [
   command=\MarginHead,
   alternative=text,
   distance=\zeropoint,
 ]

\unprotect
 \def\SIGNAL{\hskip\d_strc_itemgroups_signal}
\protect
\defineitemgroup[itemz]
\setupitemgroup[itemz][each][joinedup]

\startbuffer[Item]
 \startitemz
   \item Item
   \item Item
 \stopitemz
\stopbuffer

\starttext
 \section{No Whitespace}
 No extra whitespace before items.
 \getbuffer[Item]

 \section{Extra Whitespace} \SIGNAL
 \getbuffer[Item]
 Unexpected extra whitespace before items.
\stoptext

Pretty ugly, but thank you for that, Aditya.

Is there a similar kludge for tabulate? (That was part of my original problem, removed in the subsequent simplification of the example.)
