Defect in XSH nftw

[yyy@xxxxxxxxxxxxx (Geoff Clare)]

@ page 828 line 26942 section nftw comment [gwc nftw example]

Problem:

Defect code :  1. Error

The nftw EXAMPLE section states:

    The following example walks the /tmp directory and its
    subdirectories, calling the nftw() function for every directory
    entry, to a maximum of 5 levels deep.

However, the spec does not require that passing depth=5 limits the
depth of the walk, only that a maximum of 5 file descriptors can be
used.

Action:

Change "to a maximum of 5 levels deep" to "and using a maximum of
5 file descriptors".
