Nomenclature fixes in the lint checker. Fewer double-negatives. New style is allow(foo), warn(foo), deny(foo) and forbid(foo), mirrored by -A foo, -W foo, -D foo and -F foo on command line. These replace -W no-foo, -W foo, -W err-foo, respectively. Forbid is new, and means "deny, and you can't override it". 2012-07-27 00:08:21 +00:00			`//@ compile-flags: -D while-true`

Add a lint pass to check for while true { ... } loops And suggest changing them to loop { ... }. Had to fix the few remaining while true loops (in core::io). Closes #1962. 2012-04-20 01:04:41 +00:00			`fn main() {`
