Subject: 24.4; vc-mode and git error on newly added file to new repository
Date: Fri, 31 Jul 2015 14:43:29 +0000

At the shell make an empty git working tree and add one file to it,
but without committing, then edit it in Emacs:

% mkdir test
% cd test
% git init
Initialized empty Git repository in /home/eda/test/.git/
% echo >a
% git add a
% emacs -Q a

Type some text in the buffer, save with C-x C-s, then ask for a diff
with C-x v =.  This fails with the following text at the bottom of the screen:

-UU-:----F1  a              All L1    Git <at> master  (Fundamental) ---
fatal: bad revision 'HEAD'

-UUU:**--F1  *vc-diff*      All L1     (Fundamental from a) ----
Running git --no-pager diff-index --exit-code -p HEAD  -- a...FAILED (status 128)
