Since version 6.30 or so, comments and code blocks are correctly highlighted
when starting in columns others than 0.

I'm using that feature since then, so that my code is indented accordingly to
its position in the text.

That's not it (already tried before posting). That variable, when set, makes
Org removes the minimum common number of whitespaces.

That does not fix the problem of useless whitespaces in blank lines, and has
no impact on the indentation of tangled blocks:

Thanks anyway!
