make: Unfinished character list in pattern

[Edgar Fuß <ef%math.uni-bonn.de@localhost>]

make(1) from -11 chokes on character lists in globs ending with a hyphen:

	foo= foo bar foo-bar

	default:
		echo ${foo:M*[+-]*}

However, glob(7) says

	In order to represent itself, a `-' must either be quoted
	or the first or last character in the character list.

and this works as expected with make(1) from -10.
