From: Todd Zullinger <t...@pobox.com>
We include some perl modules which are not part of the core perl
install, as a convenience. This allows us to rely on those modules in
our perl-based tools and scripts without requiring users to install the
modules from CPAN or their operating system packages.
Users whose operating system provides these modules and packagers of Git
often don't want to ship or use these bundled modules. Allow these
users to set NO_PERL_CPAN_FALLBACKS to avoid installing the bundled
modules.
