Is there a reason behind not just detabbing (and removing trailing

separate patch anyway, might as well do all of it once and for all.

There are two reasons:

 * Main reason: it will create lots of merge conflicts for people working on the code base.
 * Minor reason: you will now be 'git blame'd for most lines of the source. It's possible to have git ignore that, but it's a source of annoyance.
