[bug #46305] Doing "find -L . -type d -delete" fails on symlinks to directories.

[Tavian Barnes]

Follow-up Comment #2, bug #46305 (project findutils):

I think this is an actual bug, despite the general danger of running -delete
together with -L.  In this setup:

$ mkdir foo
$ mkdir bar
$ ln -s ../foo bar/baz
$ find -L bar -delete
find: cannot delete ‘bar/baz’: Not a directory
find: cannot delete ‘bar’: Directory not empty

(No -type d necessary.)  strace shows that find tried to

unlinkat(AT_FDCWD, "bar/baz", AT_REMOVEDIR) = -1 ENOTDIR (Not a directory)

but "bar/baz" is not a directory so AT_REMOVEDIR is wrong.
