I wrote a Perl credential helper for netrc parsing which is pretty
robust, has built-in docs with -h, and doesn't depend on external
modules.  The netrc parser regex was stolen from Net::Netrc.

It will by default use ~/.authinfo.gpg, ~/.netrc.gpg, ~/.authinfo, and
~/.netrc (whichever is found first) and this can be overridden with -f.

If the file name ends with ".gpg", it will run "gpg --decrypt FILE" and
use the output.  So non-interactively, that could hang if GPG was
waiting for input.  Does Git handle that, or should I check for a TTY?

Take a look at the proposed patch and let me know if it's usable, if you
need a formal copyright assignment, etc.

Thanks
