build: ignore scissor line for the commit-msg hook

Browse Source 
* build-aux/git-hooks/commit-msg: Stop processing more lines when the
  scissor line is encountered.
--
This allows the command `git commit -v` to work even if the code is
longer than 72 characters. Note that comments are already ignored by the
previous line.
