Not if it directly contradicts a coding style. Every time I indent something, I have to manually cursor around and indent the whitespace.
I don't have this problem on Eclipse as it will both indent whitespace in selections as well as with the code style formatter. The same goes for any of my other editors.
This is my first time using Code::Blocks and I was very surprised as this behavior.
As far as Git is concerned, it is a non-issue either way as it has options natively to ignore whitespace changes.
