Changes to -=
The -= operator was incorrectly changed to truncate bits that didn't correspond to valid flags in 2.3.0. This has
been fixed up so it once again behaves the same as - and difference.
Changes to !
The ! operator previously called Self::from_bits_truncate, which would truncate any bits that only partially
overlapped with a valid flag. It will now use bits & Self::all().bits(), so any bits that overlap any bits
specified by any flag will be respected. This is unlikely to have any practical implications, but enables defining
a flag like const ALL = !0 as a way to signal that any bit pattern is a known set of flags.
Changes to formatting
Zero-valued flags will never be printed. You'll either get 0x0 for empty flags using debug formatting, or the
set of flags with zero-valued flags omitted for others.
Composite flags will no longer be redundantly printed if there are extra bits to print at the end that don't correspond
to a valid flag.
