Yes, I've done that - well, I called it cmex.enc, and then I referenced
it from math.enc .  It still kills TeXmacs with

Fatal error: Font not found in 'math_font_rep::search_font'

but I /have/ seen the "Please wait ..." popup for cmex.

Alright, I'll just use those stretch_boxes that were mentioned earlier. 
First and foremost, however, I would like to /see/ those brace
"corners".

Wow ! It isn't ?  Can you please show me some LaTeX-generated PDF to
that effect ?  Not that I don't believe you, I'm just curious to see
