[PATCH] Fix the objects b and B matching in doc

[Han Pingtian <hanpt@xxxxxxxxxxxxxxxxxx>]

From the example blow:

         ... ... To fix this, one would use ‘B:[nN][oO]=’ instead of
the first part. As described above, this matches at the beginning of
the trial completion, independent of other characters or substrings at
the beginning of the command line word which are ignored by the
same or other match-specs.

and the source code, I think we need this patch. Please have a look.
Thanks.
