Hi Andrey, OK, did it and got 

penrose:/tmp# cat out | /home/bob/.TeXmacs/plugins/pnambic/bin/p_out
[02]verbatim:[0a]
Maxima 5.13.0 http://maxima.sourceforge.net[0a]

  , y=-\sqrt{4\*\pi+\mathe^2+4\*\mathe+16}+\mathe+5 \right]]  , [0a]

and 

bob@penrose:/tmp$ cat in
solve([y=x^2-%e*x-%pi,y=2*x+3],[x,y]);

So, from what I can see there are no blue angle brackets after the x
coordinate of the solution coming from maxima.

Any other suggestions?

Thanks, Bob
