Apply rev 1.24 from FreeBSD's copy of this file.  Commit message from
FreeBSD:

   The algorithm that computes the tables used in the BM search
   algorithm sometimes access an array beyond it's length. This only
   happens in the last iteration of a loop, and the value fetched is
   not used then, so the bug is a relatively innocent one. Fix this by
   not fetching any value on the last iteration of said loop.

This is the cause of bug #1194393 (crash in darcs on Windows).
