 The "Subject: " line is supposed to concisely describe what the
 commit is about in one line of text.
 
-A line that mainly consists of scissors (either ">8" or "8<") and
-perforation (dash "-") marks is called a scissors line, and is used to
-request the reader to cut the message at that line.  If such a line
-appears in the body of the message before the patch, everything before it
-(including the scissors line itself) is ignored. This is useful if you
-want to begin your message in a discussion thread with comments and
-suggestions on the message you are responding to, and to conclude it with
-a patch submission, separating the discussion and the beginning of the
-proposed commit log message with a scissors line.
-
 "From: " and "Subject: " lines starting the body override the respective
 commit author name and title values taken from the headers.
