PS: While we're about it, can we please fix the expansion of « a/*/b/c/d/*

call readdir on dirs matching a/*/, a/*/b/, or a/*/b/c/.

It already does this.


$ find . -print

Running `echo a/*/b/c/d/*' calls opendir(2) twice:

$ ./bash ./x1
opendir: a/
opendir: a/x/b/c/d
a/x/b/c/d/1 a/x/b/c/d/2 a/x/b/c/d/3 a/x/b/c/d/4 a/x/b/c/d/5
