Yeah.  Just to brief here, the main reason was that one of the fields
(full page writes) already had a single space and then we had prior
cases as mentioned in Justin's email [1] where we use two spaces which
lead us to decide using two spaces in this case.

Now, we can change back to one space as suggested by you but I am not
sure if that is an improvement over what we have done.  Let me know if
you think otherwise.
