Comment:

 I love ISO specs...

 Ok, so the spec says that _if_ removing the given edge two faces become a
 single face, then the function creates a new face and returns its
 identifier.

 ... but it doesn't say what does the function return when removing the
 edge doesn't heal any face ...

 I guess we could return the identifier of the face on both sides of the
 edge being removed, but we could also return null to signal the special
 case (or how do you tell if what you get back is a _new_ or an existing
 face?).

 Opinions ?
