This sounds like it could be a bug in Getopt::Long; pod2text specified a
linkage of "termcap|t!", which should have allowed --notermcap.  Not sure
why that didn't work right.

I had the bright idea of defaulting to using termcap information if stdout
was a tty.  Not a good idea unless someone wants to do the work to make
sure it works on VMS, Win32, etc., which I can't as I don't have access to
anything that isn't a Unix.

Let's back out of this for the release.  We can always revisit it later.
