I think in a previous thread, you mentioned that you use nvi. 
While I can't speak to the knobs-and-dials that nvi offers, in 
vim, you can twiddle the 'expandtab' option (along with the 
associated 'tabwidth' and 'shiftwidth' settings) to get whatever 
behavior is deemed "correct" for the project you're working on. 
So if I'm working on a project with PEP-8 4-spaces-per-indent, I'll

   :set sw=4 ts=4 et

and then if the file erroneously has tabs in it, I'll just issue

   :retab

to fix it[1].

Yes, if you have string literals with tabs that you want to keep 
in them, the solution is a little more complex, but doable; 
though in such cases I'd recommend using "\t" instead of a 
literal tab.
