interlaced overbrace and underbrace

interlaced overbrace and underbrace

[mf]

Hello list,
is there a better way to interlace overbraces and underbraces like this?

\starttext
These are the expressions to combine:

$$\overbrace{a+b+c}+d \quad a+\underbrace{b+c+d}$$

This is the desired result:

$$\overbrace{a+b+c}+d \kern-16mm\underbrace{\hbox to 15mm{ }}$$

\blank
{\tfx(the underbrace should move down a little more)}
\stoptext

TIA,
Massi

the best i can so is to provide more options (one day drawing these 
things might come to a grinding halt because of them)


\starttext

\startbuffer
$a + \doublebrace[lt=1em]         {b+c+d} + e$\blank
$a + \overbrace  [lt=1em]         {b+c+d} + e$\blank
$a + \underbrace [lt=1em]         {b+c+d} + e$\blank
$a + \doublebrace[rb=1em]         {b+c+d} + e$\blank
$a + \overbrace  [rb=1em]         {b+c+d} + e$\blank
$a + \underbrace [rb=1em]         {b+c+d} + e$\blank
$a + \doublebrace[lt=1em,rb=1em]  {b+c+d} + e$\blank
$a + \overbrace  [lt=1em,rb=1em]  {b+c+d} + e$\blank
$a + \underbrace [lt=1em,rb=1em]  {b+c+d} + e$\blank
$a + \doublebrace[lt=-4em,rb=-4em]{b+c+d} + e$\blank
\stopbuffer

\typebuffer[option=TEX]

\getbuffer

\stoptext

so, lt for lefttop etc
