Summary:  does not descend /proc/<N>/fd

Original Submission:  This bug's happening with findutils 4.1.20 and 4.2.7,
on several different systems running linux kernel 2.6.[7-9].

The command "find /proc/1" executed as root gives this:

/proc/1
/proc/1/task
/proc/1/task/1
/proc/1/task/1/fd
/proc/1/task/1/fd/10
/proc/1/task/1/environ
[...]
/proc/1/task/1/wchan
/proc/1/fd
/proc/1/environ
[...]

as seen, it does not descend to /proc/1/fd, even though it
does have a file inside. The command 'find /proc/1/fd' gives
this output:

/proc/1/fd
/proc/1/fd/10

Similar things happen when executed as a normal user. A
'Permission denied' error message is given for
/proc/1/task/1/fd, but no error is printed for /proc/1/fd,
which has the same permissions (dr-x------).

The bug happens with any process ID, not just PID=1, for
example, try this from a bash:
find /proc/$$ ; echo ; find /proc/$$/fd

On Linux 2.4 kernels, which lack /proc/<NUM>/task, find
behaves correctly.
