Subject: Add --dry-run option to git-send-email
X-Git-Tag: v1.4.4-rc1~90^2
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=6130259c30695d8a6ceda414a7d0d14183491e82;p=git.git

Add --dry-run option to git-send-email

Add a --dry-run option to git-send-email due to having made too many
mistakes with it in the past week.  I like having a safety catch on my
machine gun.
