find . -delete gives an error message for the . directory entry

[Ari Sundholm]

Hello!

Busybox (git HEAD) seems to give an error when doing a "find . -delete"
within a directory:

------------------>8-------------------------------------------------
~/busybox/foobarbaz$ ls
~/busybox/foobarbaz$ find
.
~/busybox/foobarbaz$ find . -delete
~/busybox/foobarbaz$ echo $?
0
~/busybox/foobarbaz$ ../busybox find . -delete
find: .: Invalid argument
~/busybox/foobarbaz$ echo $?
0
------------------>8-------------------------------------------------

This error is not given by the findutils version, as shown above.
Strangely enough, the error is not reflected in the return value. This
happens also when the directory is non-empty.

Best regards,
