That was a deliberate change in order to catch cases where the end of a
range was accidentally omitted.

The wording in make's manual page doesn't refer to glob(7), it doesn't
even suggest what the semantics of the "standard shell wildcard
characters" might be. And in fact, make(1)'s :M modifier differs from
glob(7) in many more edge cases.

You can write :M*[-+]* instead.

$ make -v '${:U a +b ,c -d :M*[-+]*}'
