Surely shell globbing automatically escapes specials?

jules@pear [7] cd temp
jules@pear [8] touch "A B"
jules@pear [9] touch "A&B"
jules@pear [10] touch "A;B"
jules@pear [11] ls
A B  A&B  A;B
jules@pear [12] for item in *; do echo $item; done                      
A B
A&B
A;B

works for me (TM)

I think bash does respect IFS, but I think that globbing knows about it..

("for item in `ls`; do echo $item; done" does get tripped up by the
space, though)
