The documentation for the result values of curses functions inch() and scrbkgd() or how to use those result values are omitted entirely.  Documentation should at least describe how to use the result values of these functions without necessarily describing the actual format of the results, which do differ depending on the implementation of curses being used.

A suggestion for the documentation change is attached.

A separate issue will be filed questioning the need to shift the pair number result of the curses.pair_number() function in the Windows terminal environment.
