expect 5.39 import

[Michael Elizabeth Chastain]

Wow, I didn't even know the new expect release.  I gotta give
that a spin.

I've been using expect 5.38 in my test bed and it's been working fine. 
Back in January 2003, I compared expect 5.38 with sourceware expect,
and the gdb test results were the same.

Can you file a PR and then I'll attach my attestation to it?

By the time "a few weeks" comes up I'll have something to say about
expect 5.39 too.
