sort: Consider end field in keydef when additional fields are present

Currently, if the delimiter is found after the last field of a keydef,
only up to the beginning of the field is considered. This breaks `sort
-k N,N`, as well as whenever the sorted order comes down to that last
field.

Thanks to Richard Ipsum for the bug report and proposed patch.
