Subject: wikiheaders: Escape backslash in man pages
Otherwise, groff will interpret it as a macro, causing the man page
for SDL_GetPrefPath() to be mis-rendered. Escape unescaped backslashes
as `\(rs` ("reverse solidus") before escaping other characters with
macros that, themselves, contain backslashes.
