[PATCH]multiple wildcards ? at the end of search pattern return incorrect hits

[Xiaozheng Ma]

Hi all,

I sent a patch regarding wildcard search a couple of days ago(that was
my 1st time sending anything to the list). I've seen no response so far.
Not sure if it has been received by any of you. On the other hand, based
on what I see these two days, you guys usually response to issues
promptly. 

The problem is if you search on "ca??", the hit includes 'cat', 'CA',
etc, while the user only wants 4 letter words start with CA, such as
'card', 'cash', to be returned. This happens only when multiple '?' at
the end of search pattern. The solution is to check if the word that is
matching against search pattern ends while there is still '?' left. If
this is the case, match should return false. 

The patch file is attached and here is the text copy:
