+is used.  In that case the suggested commit message is only the message

+the message.  The contents (patch) of the "fixup -c" commit are still
+incorporated into the folded commit. If there is more than one "fixup -c"
+commit, the message from the last last one is used.  You can also use
+"fixup -C" to get the same behavior as "fixup -c" except without opening

 'git rebase' will stop when "pick" has been replaced with "edit" or
 when a command fails due to merge errors. When you are done editing
