help: mark boolean flags with [no-] to explain that they can be negated
That is, help gets tweaked thus:
global options ([+] can be repeated):
-v --[no-]verbose enable additional output
Other proposals have included:
global options ([+] can be repeated, options marked [?] are boolean flags):
-v --verbose[?] enable additional output
and
global options ([+] can be repeated, options marked [^] are boolean flags):
-v --verbose[^] enable additional output
which avoid the unfortunate visual noise in this patch. In this
version's favor, it's consistent with what I'm used to seeing in man
pages and similar documentation venues.
demandimport: error out early on missing attribute of non package (
issue5373)
If the parent module isn't a package, all valid attributes must be obtained
from it. We can raise ImportError early if any attributes not found.
demandimport: add 'nt' to ignore list (
issue5373)
pathlib2 tries to import nt. Since it is a built-in module, there should be
no performance penalty.

demandimport: add '_ctypes.pointer' to ignore list on PyPy
The pointer module is shadowed by a subsequent import. Our demand importer
can't handle this because both sub modules and attributes live in the same
namespace.
