I believe this has been discussed before, but someone might correct me.  I
believe it was decided not to replace tabs by spaces and/or to require using
only spaces going forward.  (But I don't recall all the reasons.)

I, for one, would like to see the tabs replaced by spaces in the Lisp code that
is shipped.  It's not a big deal, but I invariably find myself later cleaning up
pieces in code of mine that might have parts originally copy+yanked from vanilla
code.

But like I say, not a big deal at all.
`C-x h M-x untabify', and you're done.
