Subject: [PATCH] Add a test for pasting a multi-line commit message into the
 summary

If you paste a commit message into the summary with the terminal's
paste command, the description starts with an empty line. The first
newline of the pasted text moves to the description, and the second
one (the blank line between subject and body) is typed into the
description. Git strips the empty line when committing, but it looks
broken in the panel.
