Procedurally: please  let's not do -anything- immediately.
Wait until we have consensus.

Second, on readability and comprehensibility, I find two spaces is
simply too little. Try reading glibc code sometime; two spaces is just
not enough.  _If_ we decide to change, and M$ data says four spaces
are as legible as two, I put in a strong plea for four.
