Change coding style

This is the coding style used in Plan 9. Eschewing the whitespace
here has several large benefits:

 1. Control constructs are much easier to type.

 2. Long conditions are very naturally handled:

	if(bla && bla && bla
	|| yada && yada && yada)

    Because "if(" and "|| " (or "&& ") are the same length, the
    two parts of the condition are aligned.

 3. It becomes much less bothersome to convert a single-statement
    body to a multiple-statement body. It may seem minor, but the
    extra space is extra work.
