I did try the beta with that example and it worked, of course.  But if
I add a second \startC ... \stopC section, then it breaks.  For
example, this code (also attached as tadtest0.tex):

============================================================
\enabletrackers[buffers.visualize]

\starttext

\definetyping[C] % [option=C]
\setuptyping[C][escape=yes]

\startC
#include <stdio.h>
int main(){
    return 0;
    /BTEX{\em unreachedCode;}/ETEX
}
\stopC

\startC
printf("The second C segment doesn't work.\n");
\stopC

\stoptext
============================================================

Produces this output:

============================================================

* Verbatim Text with Embedded Formatting Commands (MkIV)

As noted at 
http://wiki.contextgarden.net/Verbatim_text#Embedded_formatting_commands, 
the embedded formatting commands in verbatim text don't work in MkIV.

Are there any plans to fix this capability soon?  I'm planning on 
working on a project on over the holiday break that will need it.

I'm not pushing to change your priorities.  If it's not going to be 
fixed soon, then I'll implement a simple verbatim module that supports 
embedded formatting commands that will do until the official module 
works.  I just don't want to waste that effort if verbatim is going to 
be fixed soon anyway.

Thanks,
Tad Ashlock
