Subject: [PATCH] wikiheaders: Fix manpages for APIs that return a pointer to a
 const object.

Previously something like SDL_GetCurrentDisplayMode() would have this output:

RETURN VALUE
*) Returns a pointer to the desktop display mode or NULL on failure; call SDL_GetError() for more information.


Now it doesn't have the junk at the start of the text:

RETURN VALUE
Returns a pointer to the desktop display mode or NULL on failure; call SDL_GetError() for more information.
