[cl-debian] Bug#331160: common-lisp-controller: Warning from 'find' in maintainer scripts output on upgrade

[debian at millenix.mailshell.com]

Package: common-lisp-controller
Version: 4.19
Severity: normal

In the process of upgrading common-lisp-controller from 4.18 to 4.19
(and I actually saw this earlier, assuming it would be fixed), I see the
following text:
----
Preparing to replace common-lisp-controller 4.18 (using
.../common-lisp-controller_4.19_all.deb) ...
find: warning: you have specified the -depth option after a non-option
argument -type, but options are not positional (-depth affects tests
specified before it as well as those specified after it).  Please
specify options before other arguments.
----

It looks like the third call to find in the preinst script (see below
for excerpt) is what's setting this off, but I'm not sure if simply
moving the options around would do the right thing.

Here's the segment of code in question:
----
case "$1" in
    install)
    ;;
    upgrade)
        # cleanup fasl files:
        find  /usr/share/common-lisp/source/defsystem
/usr/share/common-lisp/source/asdf
/usr/share/common-lisp/source/common-lisp-controller -type f -not
-name "*.lisp" -print0 | xargs --null rm --force 2> /dev/null
        # remove old autobuild files:
        find /etc/common-lisp -name autobuild -print0 | xargs -0 rm 
2> /dev/null || true
        find /etc/common-lisp -type d -depth -print0 | xargs rmdir 2>
/dev/null || true
... etc, it goes on
----                         ^^^^^^^^^^^^^^^^
I believe that the snippet marked above is what gives rise to this
warning.
