[PATCH 3/3] wildmatch: hide internal return values

[Phillip Wood <phillip.wood123@gmail.com>]

From: Phillip Wood <phillip.wood@dunelm.org.uk>

WM_ABORT_ALL and WM_ABORT_TO_STARSTAR are used internally to limit
backtracking when a match fails, they are not of interest to the caller
and so should not be public.
