BSD grep fixes

Other important differences between bsdgrep and GNU grep:

The --include option in bsdgrep does not have the same effect as the
corresponding option in GNU grep -- in GNU grep, that option causes
_only_ those files matching the file inclusion pattern to be searched.
 To obtain the same behavior in bsdgrep, one must issue something like
--exclude '*' --include pattern.

The effect of multiple overlapping --include and --exclude options is
different in the two greps.  It would be wise to add comments about
precedence of such options in the bsdgrep manpage, as is done, for
example, in bsdtar(1).
