First the grouped parts of RewriteRule pattern matches (parenthesis!) can be
accessed now via backreferences $1..$9 in RewriteConds test-against strings in
addition to RewriteRules subst string. Second the grouped parts of RewriteCond
pattern matches (parenthesis!) can be accessed now via backreferences %1..%9
both in following RewriteCond test-against strings and RewriteRules subst
string. This provides maximum flexibility through the use of backreferences.
Additionally the rewriting engine was cleaned up by putting common code to the
new expand_backrefs_inbuffer() function.
