pre-rebase hook: capture documentation in a <<here document




From: Jonathan Nieder <jrnieder@xxxxxxxxx>

Without this change, the sample hook does not pass a syntax check
(sh -n):

  $ sh -n hooks--pre-rebase.sample
  hooks--pre-rebase.sample: line 101: syntax error near unexpected token `('
  hooks--pre-rebase.sample: line 101: `   merged into it again (either directly or indirectly).'

Our internal release of git @ Google is debian experimental,
which is basically the 'next' branch + this patch + another patch.

AFAICT It is a resend of
https://public-inbox.org/git/20120308122105.GA1562@burratino/

As Jonathan is a Debian Developer, it is easy for us to base
our internal version onto debian experimental, but long term we may
want to base our internal version on the original next. :)
To do so, upstream this one last meaningful patch.

The 'another patch' from above is changing and hardcoding
the version number, which we do not want to upstream.

Thanks,
Stefan
