compilation-next-error - extra `let' binding?

[Drew Adams]

Can't tell for sure without checking all of the code called by the
body of the `let', but it looks like the `let' binding of `loc' in
`compilation-next-error' is superfluous:
 
(let* ((msg (get-text-property pt 'message))
       (loc (car msg)) ; ???????
       last)
 
If so, taking out the binding would make the code easier to
understand. If not, adding a comment for it might make the code easier
to understand.
