minor tweaks for `python-check'

* lisp/progmodes/python.el (python-check-custom-command): Buffer local
because it usually includes the buffer name.
(python-check-command): Set to epylint when pyflakes is not available.

etc/NEWS: Document EUDC improvements

EUDC: New maintainer

net/eudc-hotlist.el, net/eudc-vars.el: New maintainer.

isearch.el (isearch-process-search-char): Add docstring.

Auto-commit of loaddefs files.

lisp/emacs-lisp/derived.el (define-derived-mode): Declare indent 3.

Now, e.g. `indent-sexp' will produce:

    (define-derived-mode outline-mode text-mode "Outline"
      "Set ...")

instead of:

    (define-derived-mode outline-mode text-mode "Outline"
                         "Set ...")

Port autogen.sh hook creation to Apple Git

* autogen.sh: Do not assume that the hook samples exist.
This ports to git version 1.9.3 (Apple Git-50).
For some reason Apple decided to populate the git hooks directory
in a different way from the way that standard Git does it.
The downside is that patch applications won't be checked on Apple,
but that's better than autogen.sh failing.

Avoid a crash when the daved ptr is at the end of the list (= when it's
before the first one).  Also use `eq' to compare the value so the saved

than an equal result is shown.
