Thanks for correcting the indentation :)

About tab vs spaces, I didn't notice(or care) this before. I searched
about tab vs spaces and found something interesting
here(http://gcc.gnu.org/ml/libstdc++/2008-07/msg00161.html).

So should I later propose a single patch to make every 8 spaces to a
tab, or just make changes for all my committed files in this patch?
