Yes you can do that.  I think Mr.Berg gave some similar code in this
thread.

Be careful though about accidentally wrecking files.  I notice you've
exempted makefiles, which is a good idea.  You might want to exempt
more, like config files.

If you're doing work on a VC system with others then changing tabs
becomes a major irritation.  That's because it creates a lot of false
changes (i.e. line changes where the code hasn't really changed).
