Why are you doing this manually?  Emacs does that for you, as soon as
you set indent-tabs-mode to a non-nil value.  .dir-locals.el in the
Emacs Git repository should do that automatically; it already does on
the release branch and soon will be doing that on the master branch as
well.  And to reformat existing code, make a region around it and
invoke "M-x tabify".

There should be no need to insert tabs and spaces manually.
