brace error after a \placefigure

brace error after a \placefigure

[Sanjoy Mahajan]

I can't figure out what causes the brace error with this test.tex
example file:

\starttext
\placefigure[margin]{A caption}{\externalfigure[]}

{test}.
\stoptext

$ texexec test
  [...]
  ! Too many }'s.
  l.4 {test}
	    .
  ? H
  You've closed more groups than you opened.
  Such booboos are generally harmless, so keep going.

If I change 

{test}.

to

The {test}.

then it compiles fine.

$ texexec --version

Yes, strange. Looks like a grouping issue around this in page-flt:

    \ifmargeblokken % waarschijnlijk gebroken ! ! ! !
      \doifinset\v!margin{#2}
        {\endgraf
         \bgroup\everypar{\egroup\the\everypar}%
         \hsize\@@mbwidth}%
    \fi

inmargin seems to work, but i don't know if it should do the same thing.

Yes.

It works ok with

   \leavevmode {test}.

Also. The problem is the timing of \everypar, what TeX actually
executes is this:

    \bgroup
    \everypar {\egroup}
    \par
    {test}

Cheers, Taco

no, the margin option collects graphics in the margin

may work better
