Yet another problem with bzr and diff formats:

For Lisp files it's useful to set vc-bzr-diff-switches to "-F ^("
or diff --diff-options '-F ^(' aka `--show-function-line'
to show a function/variable name that precedes the hunk
(like "@@ (defvar ispell-message-text-end" in the patch below).

But in this case, with (add-hook 'message-send-hook 'ispell-message)
`ispell-message' checks the spelling of the whole patch that is annoying.

`ispell-message-text-end' defines the limit of spell-checking
for unidiff/context diff formats.  But it is too strict.

This patch removes the final newline to allow more text after @@:
