UniqueMPgraphic and empty lines

UniqueMPgraphic and empty lines

[Patrick Gundlach]

Hi,

is it a bug or a feature?
-------------------------------------------
\defineoverlay[myhead][\uniqueMPgraphic{mphead}]
\startuniqueMPgraphic{mphead}
w := \overlaywidth;
h := \overlayheight;
path p;
p:=  (0,.1w){left} .. {right}(0,0) .. (.5w,.2h) .. (w,0){right}
     .. {left}(w,.1w);
%
draw p shifted (0,.1h);
draw p reflectedabout ((-infinity,0),(infinity,0));
draw boundingbox currentpicture;
\stopuniqueMPgraphic

\starttext

\framed[background=myhead]{BlaBlaBlubb}

\stoptext
-----------------------------------------------

If I remove the % sign, texexec gives me an error (runaway 
argument).

By redifining 
\def\handleuniqueMPgraphic#1#2#3%
[...]

to 
\long\def\handleuniqueMP.....

it works ok. But I do not know if that has any side effects.

Viele Grüße,

Hi all,

Actually, I'd be happy if we could change the primitive meaning of \def to 

\def\def{\long\def} 

And likewise redefinede \outer as a no-op 
\def\outer{}

Unf, it is not safe to do this in good old tex (expansion problems), but it
could
be done in etex ...

indeed, unfortunately this will break unless maybe:

\let\normaldef\def

\unexpanded\def{\long\normaldef}

since this will not expand so often

well, \outer *is* a no-op in context, even plain is loaded under that 
assumption,

I always thought this was the default in ConTeXt already??

Only while reading plain.tex

(but yes, there are no \outer control sequences in context)
