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.

> Both of these problems were already dealt with in commit r3714, on June
> 3rd. Confused why you're posting patches for them now. [[done]] --[[Joey]]
