Log Message:
pkglint says, the :Q operator should not be used in double quotes.

The code here only worked due to many conincidences: Let's assume a
variable has the value "a b" and is used with the :Q operator, which
results in "a\ b" (a, backslash, space, b). When used in double quotes,
the shell command looks like:

    echo "a\ b"

which, depending on the shell, may output the backslash literally or
not. In the case of this file, the ":Q" string was not passed to
echo(1), but to sed(1). sed(1) in turn interprets (backslash, space) in
the replacement text as equivalent to (space), and that's where the
backslash finally disappears. So it's only to this coincident that the
code worked although it was not correct.
