Well, this discussion has probably been made a few times, but I can't
find a thread.

First, some facts:
- Whitespace cleanup considers 8 (and only 8) spaces to be
a tabulation, and discards the fact that `tab-width' could have been
changed.
- On the contrary, `tabify' uses `tab-width'.

And  this is  inconsistent, as  I  see whitespace-cleanup  as a  super
tabify.delete-trailing-whitespace.do-some-magic function.

Second, a « mylife » part:
My company uses « tab » as indentation char. Not two spaces, not
whatever, but tabs. And it looks, well, IMHO, awful. For MY (very own)
eyes, I wish I could see tabs as 2 spaces, and this is hopefully
possible in the Mighty Editor by setting `tab-width' to 2.

Is it completely politically incorrect (or simply wrong) to consider
such a patch :
