Using command in section

["Martin Kolařík" <martin@mii.cz>]

Hi all,

I'm using private macro for title of section:

\setuphead[section][command=\doTitle]

and if I typeset inside this \doTitle#1#2 something like (test code):

\vbox to 0pt{
  \hsize=3cm
  \hbox{\vtop{#1}\vtop{#2}}
  \hbox{\vtop{X} \vtop{The quick brown fox jumped over the lazy dog.}}
  \vss
}

I get two boxes -- the first (made from #1 and #2) NOT aligning the first
lines of vtop's (#1 is higher) and the second, which is aligned as I
expect -- both "X" and "The quick..." in the one "line".

So I traced data coming into #2 and content of \vtop filled with it and I
saw the #2 contains some vertical glue at the beginning.

What should I do to avoid this behaviour? (excluding splitting of the
resulting box using low level TeX primitives :-),

have a nice day and thanks,

Martin
