Something is wrong in this patch.  It looks like it is introducing the
code that you wanted to remove.

In the commit message, there should be a space after the period.  It is
not clear what "For example:-" means.  If it is part of the same sentence
as the next line, then tIts in the next line should not be capitalized.

Did Greg not accept the previous version of this patch?
