Why not

RewriteRule ^list/([^/]*/)([0-9]+) list.php?r=$1$2 [QSA]
RewriteRule ^content/(.*) content.php?r=$1 [QSA]
RewriteRule ^widget/config/([0-9]+) widget.php?r=config/$1 [QSA]

as it is used in the lines before? [QSA] does just that - it appends the existing Query String.

This line can't work - $1 and $2 are references to bracketed expressions - but there are none...

The original line for Apache 2 is

RewriteRule ^(?:(.*?)(?:/|$))(.*|$)$ $1.php?r=$2 [QSA]

and can be "translated" to

RewriteRule ^((.*?)(/|$))(.*|$)$ $2.php?r=$4 [QSA]

which is equivalent.
