+2011-10-28  Alan Mackenzie  <acm@muc.de>
+
+        Amend to indent and fontify macros "which include their own semicolon"
+        correctly, using the "virtual semicolon" mechanism.
+
+        * cc-defs.el: Update "virtual semicolon" comments.
+
+        * cc-engine.el (c-crosses-statement-barrier-p): Recoded to scan one line at
+        at time rather than having \n and \r explicitly in c-stmt-delim-chars
+        (for some modes, e.g. AWK).
+        (c-forward-label): Amend for virtual semicolons.
+        (c-at-macro-vsemi-p, c-macro-vsemi-status-unknown-p): New functions
+
+        * cc-fonts.el (c-font-lock-declarations): Take account of the new C macros.
+
+        * cc-langs.el (c-at-vsemi-p-fn, c-vsemi-status-unknown-p-fn): move to
+        earlier in the file.
+        (c-opt-cpp-symbol, c-line-comment-start-regexp): New language variables.
+        (c-opt-cpp-macro-define): Make into a full language variable.
+        (c-stmt-delim-chars, c-stmt-delim-chars-with-comma): Special value for
+        AWK Mode (including \n, \r) removed, no longer needed.
+
+        * cc-mode.el (c-mode, c++-mode, objc-mode): Invoke
+        c-make-macro-with-semi-re.  (Erroneously committed early, in previous
+        version, 5.259.)
+
+        * cc-vars.el (c-macro-with-semi-re, c-macro-names-with-semicolon): New
+        variables.
+        (c-make-macro-with-semi-re): New function
+
+        * cc-mode.texi (Indentation Commands): Mention "macros with semicolons".
+        (Other Special Indentations): Add an xref to "Macros with ;".
+        (Customizing Macros): Add stuff about syntax in macros.  Add an xref to
+        "Macros with ;".
+        (Macros with ;): New page.

+
+        * vc/log-edit.el: Fill empty field rather than adding new one.
+        (log-edit-add-field): New function.
+        (log-edit-insert-changelog): Use it.
+
+2011-10-28  Mark Lillibridge  <mark.lillibridge@hp.com>  (tiny change)
+
+        * mail/rmail.el (rmail-mode-map): Add M-C-f as in rmailsum (bug#9802).
+
+2011-10-28  Stefan Monnier  <monnier@iro.umontreal.ca>
