My guess is that the repository was created by an older version of Git.  
Git versions before 1.6.0 didn't create .sample files for hooks.
In previous discussion about this, we thought it OK to require Git 
version 1.7.1 (April 2010) or later; see the (admittedly short) thread 
at 
<http://lists.gnu.org/archive/html/emacs-devel/2014-12/msg00037.html>. 
If this needs to be revisited, now's as good a time as any to do that.

It's a hook for when you apply patches from other developers.  The 
simplest thing to solve just this problem, assuming you're running a 
recent-enough Git, is to reclone the repository from scratch.  You 
should be able to patch an existing repository built with an older Git 
by running 'chmod a+x .git/hooks/applypatch-msg 
.git/hooks/pre-applypatch; cp .git/hooks/applypatch-msg 
.git/hooks/applypatch-msg.sample; cp .git/hooks/pre-applypatch 
.git/hooks/pre-applypatch.sample' (though I haven't tested this).
I installed the attached patch to INSTALL.REPO to try to help clarify 
the situation a bit.
