dot to be considered as a word delimiter?

Currently it seems like that dot is not considered as a word delimiter
by the english parser.

lawdb=# select to_tsvector('english', 'Mr.J.Sai Deepak');
to_tsvector
-------------------------
'deepak':2 'mr.j.sai':1
(1 row)

So the word obtained is "mr.j.sai" rather than three words "mr", "j",
"sai"

It does it correctly if there is space in between, as space is
definitely a word delimiter.

lawdb=# select to_tsvector('english', 'Mr. J. Sai Deepak');
to_tsvector
---------------------------------
'j':2 'mr':1 'sai':3 'deepak':4
(1 row)

I think that dot should be considered by as a word delimiter because
when dot is not followed by a space, most of the time it is an error in
typing. Beside they are not many valid english words that have dot in
between.
