Merge branch 'rk/send-email-ssl-cert' into maint

A recent update to "git send-email" broke platforms where
/etc/ssl/certs/ directory exists but cannot be used as SSL_ca_path
(e.g. Fedora rawhide).

* rk/send-email-ssl-cert:
send-email: /etc/ssl/certs/ directory may not be usable as ca_path

diff --cc git-send-email.perl
Simple merge
