If you send the patch in the form of git-format-patch, those details
are taken care for you by Git.

Clément suggested a shorter wording that would fit.  I can suggest
another:

  Go to the beginning or @end of the current Texinfo environment.

You don't have to say it all in the first sentence, only the main

doc string.

Maybe so, but the current guidelines still say the above.  Feel free
to raise this issue on emacs-devel.

Thanks.
