[PATCH v2] wt-status.c: set commitable bit if there is a meaningful merge.

["Stephen P. Smith" <ischis2@cox.net>]

The 'commit --dry-run' and 'commit' return values differed if a
conflicted merge had been resolved and the commit would be the same as
the parent.

Update show_merge_in_progress to set the commitable bit if conflicts
have been resolved and a merge is in progress.
