We can do both.  I don't want to have 16 ERROR's in my face while
we are figuring this out.

Aw, foo!  That's what's different about gdb.cp/*.exp.  All the examples
in gdb.cp/*.exp are like:

  { x = 100, y = 101 }

Both the sourceware version of TCL (which is based on 8.4.1) and
the version I use of TCL (8.4.6) have code for {NUMBER} and
{NUMBER, NUMBER} modifiers.

I suspect there's some difference happening at the expect level
(5.26 versus 5.41).

Time to dive into the TCL source and throw in some fprintf's and stuff.
