extra white in framedtext

extra white in framedtext

[-- Attachment #1.1: Type: text/plain, Size: 1348 bytes --]

I did want to typeset material within framedtext with some white  
before and after each line.
Appropriate for this seems to me: \null\quad material \quad\null\crlf  
etc.; the preceding \null preventing disappearence of the first \quad.

The strange thing is that the \null in the first line induces an  
extra vertical whitespace between the top of the frame and the first  
line inside the frame.

An impression of the result:

-----------------------
|                     |  with \null in first line
|      first line     |
|      second line    |
-----------------------

-----------------------
|      first line     |  without \null in first line
|      second line    |
-----------------------

It seems counterintuitive to withhold the \null in the first line in  
order to have the framing correct.
A minimal example on which I encountered this follows:

\setupbodyfont[cmr]

% gives extra vertical white
\startframedtext[middle][width=fit]
\null\quad\type{extra vertical space}\quad\null\crlf
\null\quad\type{normal vertical space}\quad\null
\stopframedtext

% normal vertical white
\startframedtext[middle][width=fit]
\quad\type{normal vertical space}\quad\null\crlf
\null\quad\type{normal vertical space}\quad\null
\stopframedtext

\stoptext

Does this occur elsewhere too?
Is it normal behaviour of framedtext?

the width=fit option will decompose the box try - as best as can do done with current tex- determine the fittign width; 

in the process, spacing may disappear 

also, framed may place struts automatically 

this may work: 

\startframedtext[middle][width=fit]
\strut\endgraf
\type{extra vertical space}\endgraf
\type{normal vertical space}\endgraf
\strut\endgraf
\stopframedtext

as may this: (smaller strut) 

\startframedtext[middle][width=fit,strut=no]
{\setupstrut[x]\strut}\endgraf\nointerlineskip
\type{extra vertical space}\endgraf
\type{normal vertical space}\endgraf
{\setupstrut[x]\strut}\endgraf\nointerlineskip
\stopframedtext


another option is to do something: 

\framed [width=fit,offset=overlay] \bgroup
  \vskip 1ex
  \quad \framed[width=fit,frame=off] \bgroup
      your content 
  \egroup \quad 
  \vskip 1ex
\egroup

or alike

Yes, my default font setup sometimes seems to play havoc with me.
It turns automagically into lm.

As for the above problem, my brains were a bit rusty I think.
Just a leavevmode did the trick:

\startframedtext[middle][width=fit]
\leavevmode % <= the solution
\null\quad\type{with leavevmode: no more extra vertical space}\quad 
\null\crlf
\null\quad\type{normal vertical space}\quad\null
\stopframedtext

in general \dontleavehmode is better since \leavevmode may introduce unwanted whitespace sometimes

(i try to avoid \leavevmode whenever possible)

At my end (gmail), a random set of spaces from Hans van der Meer's
(such an awesome name, btw) example have turned into U+FFFD in your
reply.
