Log message:
Untaint a variable used in an sprintf format string by using a regex and back-
reference. This diff from espie@ after we worked through a few alternatives.
(Background: with perl's taint mode, any operation other than RE+backref, even
just taking a length of a tainted [user-supplied/untrusted] string, results in
a tainted variable. Perl 5.14 improves the checks in format strings to sprintf
which triggers with this script).
