[bug #26281] find -depth sometimes visits nodes in the wrong order

[James Youngman]

Follow-up Comment #2, bug #26281 (project findutils):

There is a second alternative interpretation of events, I think.   The POSIX
description for -depth is:

-depth
    The primary shall always evaluate as true; it shall cause descent of the
directory hierarchy to be done so that all entries in a directory are acted on
before the directory itself. If a -depth primary is not specified, all entries
in a directory shall be acted on after the directory itself. If any -depth
primary is specified, it shall apply to the entire expression even if the
-depth primary would not normally be evaluated.


One reading of this is that the paragraph above only requires that
"dir/m4/Makefile.am"  and "dir/Makefile.am" are both processed before "dir"
itself, but that no guarantee need be made about the relative ordering of the
visits to the two files.
