This allows find to pass files with "illegal" characters to xargs in a
safe manner.
Note: due to the manner in which the file names are now passed between
find and xargs, the files are now sorted differently than before.
The first /etc/security run after installing this change may result
in a lot of output when nothing did in fact change.
Closes PR# 1910.
2.2 candidate.
