To be able to use outline-minor-mode-cycle keys in diff-mode,
outline-minor-mode should be higher in minor-mode-map-alist,
and a new variable diff-mode-read-only should be set
when the diff-mode buffer is read-only.

* lisp/vc/diff-mode.el: Add diff-mode-read-only to minor-mode-map-alist.
(diff-mode-read-only): New buffer-local variable.
(diff-mode): Set diff-mode-read-only to t when buffer-read-only is non-nil.
Update diff-mode-read-only in read-only-mode-hook.
Remove buffer-read-only from minor-mode-overriding-map-alist.

* lisp/vc/vc.el (vc-diff-internal): Set buffer-read-only to t

Update all callers. This reverts the previous solution for bug#39452.

the version number when parsing git versions (bug#52172).

* lisp/vc/vc-git.el (vc-git-print-log-follow):
Mention caveats in a comment.
* lisp/vc/vc-git.el (vc-git-register):
Use file names verbatim with 'git update-index', as it only accepts
file names, not pathspecs (bug#39452).
* lisp/vc/vc.el (vc-print-root-log):
Expand ROOTDIR, so that vc-git-print-log doesn't receive an
abbreviated name. Literal pathspecs don't work with those.

robust (bug#49683). It could previously error out under certain
conditions, like moving directories in and out of the
VC-controlled tree.
