option=tex in setuptyping causes the background to be drawn twice

Hi,

The following minimal example:

\definetextbackground
     [EXAMPLE]
     [
           location=paragraph,
      rulethickness=1pt,
         leftoffset=5em,
        rightoffset=0mm,
     ]

\setuptyping[option=tex, before=\startEXAMPLE, after=\stopEXAMPLE]

\starttext
\starttyping
   A = B + C
\stoptyping
\stoptext

gives the attached output where the background is repeated twice. The bug 
is present with both mkiv and ltmx.

The problem are these settings in buff-imp-default.mkiv:

\setupstartstop
   [DefaultSnippet]
   [\c!before={\typingparameter\c!before},
    \c!after={\typingparameter\c!after},
    \c!style={\typingparameter\c!style}]

In buff-imp-tex.mkiv these values are inherited:

\definestartstop
     [TexSnippet]
     [DefaultSnippet]

So I can fix this locally by resetting before and after keys for 
TexSnippet. What would be a good fix in buff-imp-default?

I assume Wolfgang will cook up a patch ...

The best solution is to remove the values from all three keys because 
for now each of them is applies twice (even the style).

\setuptyping
   [before=\hairline,
     after=\hairline,
     style=\tt\em]

\starttext

\starttyping[option=tex]
\donothing
\stoptyping

\stoptext
