Subject: git-send-email: prevent undefined variable warnings if no encryption is set
X-Git-Tag: v1.6.0-rc0~177^2

git-send-email: prevent undefined variable warnings if no encryption is set

With the previous patch, not configuring any encryption (either on or
off) would leave $smtp_encryption undefined.  We simply set it to the
empty string in that case.
