Details:

A wish for m4 2.0: patsubst() and translit() builtins that can do more than
one operation in a single call. Right now, it's awkward to chain together
multiple invocations of these, and the quoting/robustness issues can get very
hairy.

I'd like to see patsubst()/translit() gain a multi-argument semantic like
ifelse(), where one could invoke e.g.

  patsubst(`$1', `meow', `woof', `apple', `orange', `blue', `red',
`POSIX_EXTENDED')
