Just what you think it means: if you requested M-x dired RET ~/foo/* RET
it called "ls --dired -al *" from directory ~/foo.

My patch just changes the code so that M-x dired RET ~/foo/*/bar RET
is turned into "ls --dired -al */bar" from directory ~/foo.

I know.  That's why ls-lisp advises the corresponding function.
