Ok, I'm currently working on a patch series for Dscho and others where I 
split up the big patch ('[PATCH 1/6] Refactor git tag objects; make "tag" 
header optional; introduce new optional "keywords" header') into babysteps.

I can:

1. Provide a new patch series to totally replace the previous 6-part patch 
series (plus bugfixes). The new patch series will make smaller steps and 
end up (hopefully) in a better place, with less overzealous 
checking/parsing, and more "traditional" whitespacing.

OR

2. Provide the babystep-series ending up exactly where we are today (i.e. 
after the patch series, plus bug fixes). Then, provide patches on top of 
the existing series to get it into shape, both scope-wise (i.e. not trying 
to do too much) and whitespace-wise.

Which do you prefer?
