Yeah.
Indent with tabs, align with spaces.

I find reading code with two or eight spaces for indentation hard to
read. However both styles are widely used.. if everybody just indented
with tabs and configured his editor to display 2/4/8/42 spaces for a tab
everybody could be happy.

The only thing that is more horrible than indentation with spaces is
mixing indentation with spaces and tabs so it's completely broken when
your editor uses another tab-width than the authors editor.
