[PATCH] Add gitattributes file making whitespace checking pickier

From: J. Bruce Fields <bfields@citi.umich.edu>

This will change the notion of "bad" whitespace for the git project to include initial whitespace that uses spaces where tabs could have been used.

This only changes which whitespace is considered "bad".  It doesn't
change the behavior when bad whitespace is found.  By default, commands
like git-apply, git-am, and git-rebase will print a warning but
otherwise do nothing.

Is there any reason not to use this now that we have it?
