Thanks for your analyse.

But I cann't figure this out, see the following results on my box:
$ echo [ -f *.cache-2 ]
[ -f *.cache-2 ]
I cann't see any differences between your code and the following one:
$ echo something and something
something and something
Could you please give me some more hints?
