Subject: send-email: fix In-Reply-To regression
X-Git-Tag: v1.5.5-rc0~169
X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=0fb7fc751d29cd1099556f71fc7c08158a6a78bc;p=git.git

send-email: fix In-Reply-To regression

Fix a regression introduced by

1ca3d6e (send-email: squelch warning due to comparing undefined $_ to "")

where if the user was prompted for an initial In-Reply-To and didn't
provide one, messages would be sent out with an invalid In-Reply-To of
"<>"

Also add test cases for the regression and the fix. A small modification
was needed to allow send-email to take its replies from stdin if the
environment variable GIT_SEND_EMAIL_NOTTY is set.
