For code consistency I think it would be better to force everything to
use the lower case "true/false".  Otherwise this patch does nothing to
force new code to use the standardized version.

There may be some exception we want to make for unmodified 3rd party
libraries that are checked in, like lib/bzlib which uses True/False,
otherwise it makes it hard to take new code drops of those things.
