[PATCH] send-email: If the ca path is not specified, use the defaults

[Igor Gnatenko <i.gnatenko.brain@gmail.com>]

From: Ruben Kerkhof <ruben@rubenkerkhof.com>

I use gmail for sending patches.
If I have the following defined in my ~/.gitconfig:
[sendemail]
	smtpencryption = tls
	smtpserver = smtp.gmail.com
	smtpuser = ruben@rubenkerkhof.com
	smtpserverport = 587

and try to send a patch, this fails with:
STARTTLS failed! SSL connect attempt failed with unknown error
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate
verify failed at /usr/libexec/git-core/git-send-email line 1236.
