+Turning the wikilink regexp into an extended regexp on the svn trunk seems to have broken the setuid wrapper on my system, because of two reasons: First, the wrapper generator should turn each newline in $configstring into `\n` in the C code rather than `\` followed by a newline in the C code. Second, the untainting of $configstring should allow newlines.
