RFA/testsuite/c++: Overhaul userdef.exp

[Michael Elizabeth Chastain]

This patch is approved, subject to (you guessed it) addition of the
year 2002 to the copyright line.

I adore this kind of overhaul, thanks.

I proofread the test script and it is all okay.

I ran this through my test bed and did a before-and-after diff.
All configurations look no worse than before.
