pmatch licensing

[Ludovic Courtès]

Hello Guilers!

We need to figure out the ‘pmatch’ license, as noted in the file.
Andy: can you take care of that?

Besides, it should be documented in the manual.

FWIW I’m not fully convinced about having this second pattern matcher.
Granted, the implementation is much simpler than Wright’s (ice-9 match),
and it provides a slightly simpler syntax (e.g., ‘guard’ vs. ‘(?
pred)’).  But AFAICS this comes at the cost of limited features (e.g.,
‘and’, ‘or’, ‘..k’, etc.).

Thanks,
Ludo’.
