   SUBSTRING is not a string-comparison function.

Yep!

   Why not allow using CHAR/CHAR-SET/PRED here?

Uhh... OK. I'm reluctant to stuff *more* functionality into the lib, but it
does preserve parallelism w/the other routines. The char case doesn't seem
very useful, but the char-set case is, and if one is going to do char-sets &
predicates, one should include the char case to stay parallel w/the other
routines in the lib.

   This comment does not belong in the final SRFI document.

Yep!

Thank you.
