+
+2013-12-25  Fabián Ezequiel Gallina  <fgallina@gnu.org>
+
+        * progmodes/python.el:
+        (python-nav--lisp-forward-sexp): New function.
+        (python-nav--lisp-forward-sexp-safe): Use it.  Rename from
+        python-nav-lisp-forward-sexp-safe.
+        (python-nav--forward-sexp): New argument SAFE allows switching
+        forward sexp movement behavior for parens.
+        (python-nav-forward-sexp): Throw errors on unterminated parens
+        (Bug#16191).
+        (python-nav-backward-sexp, python-nav-forward-sexp-safe)
+        (python-nav-backward-sexp-safe): New functions.
+        (python-shell-buffer-substring): Use

+        (shr-find-fill-point): Remove the special checks for the quotation
+        mark, since `shr-char-kinsoku-bol-p' should now return the right
+        thing.
