Upstream changes:
version 0.014; 2014-02-06
* bugfix: suppress any CORE::GLOBAL::require override, where possible,
to avoid use_package_optimistically() being misled into treating
missing modules as broken
* bugfix: in use_module() and use_package_optimistically(), pass a
supplied VERSION parameter through for the version check even if it
is undef
* tighten use_package_optimistically()'s recognition of can't-locate
errors (the same way that base.pm has recently been tightened),
so that, when a module fails to load because a module that it uses
isn't available, the outer module will be perceived as broken rather
than missing
* update documentation notes about the state of Unicode handling for
module names
* in META.{yml,json}, point to public git repository
