the arguments are nil.

Document mml-secure-safe-bcc-list.

Fix misspelling of “matching”.  Use @table for table.

Preserve key bindings that shr adds (bug#23964).

(buffer-substring--filter): Add a link to 'with-wrapper-hook' as

obsolete facility.

* nt/README.W32: Add URL of Emacs dependencies on alpha.gnu.org.

* lisp/frame.el (blink-cursor-check, blink-cursor-mode):
Protect ourselves against too small values of blink-cursor-delay.
This avoids erratic display of the cursor, or even failure to
display it, when user types text at high speed or leans on a key
to invoke the keyboard auto-repeat feature.  (Bug#24372)

of a literal period.  (Bug#24407)

This was backported from master
(cherry picked from commit 71238966)

comparing it to zero (Bug#24281).

This was backported from master

that debugger code that needs to do regexp match won't break

This was backported from master
(cherry picked from commit 7fb75680)

* lisp/mouse.el (mouse-drag-track): Reset deactivate-mark in the
buffer of the drag event, to allow mark to be set and the region
be shown as we drag the mouse.  (Bug#24030)

This was backported from master
(cherry picked from commit 7d58b02f)

* src/xdisp.c (move_it_in_display_line_to): Don't assume we can
wrap on a whitespace character if it's followed by another
whitespace character.  When returning under WORD_WRAP for a screen
line that is continued, restore to wrap point when atpos/atx
position would be displayed on the next screen line due to
line-wrap.  (Bug#23570)

This is backported from master
(cherry picked from commit 99848b37)

Problem reported by Glenn Morris (Bug#19889).

ability to find Lisp primitives by their C name, which was lost
when the etags back-end was switched to a more strict search
criteria.

* test/etags/ETAGS.good_2:
* test/etags/ETAGS.good_3:
* test/etags/ETAGS.good_4:

parameters restored by desktop.el take precedence over the

that.  For the details of the issue, see
http://lists.gnu.org/archive/html/emacs-devel/2016-09/msg00318.html.
