+2020-04-10 Eli Zaretskii <eliz@gnu.org>
+
+ Fix redisplay when scrolling under redisplay-dont-pause
+
+ * src/dispnew.c (update_window): Reset the window's

+
+ Avoid assertion violation in intervals.c
+
+ * src/intervals.c (delete_interval): Allow negative values of

+2020-04-08 Dmitry Gutov <dgutov@yandex.ru>
+
+ Speed up 'resize-mode' child frames a little
+
+ * src/gtkutil.c (xg_frame_set_char_size): Skip resizing if the
+ target dimensions are unchanged for child frames with
+ 'resize-mode' resize policy as well.
+
+2020-04-06 Martin Rudalics <rudalics@gmx.at>
+
+ Fix some problems with moving and resizing child frames
+
+ (1) Provide new option 'x-gtk-resize-child-frames' which allows
+ to either hide a child frame during resizing or asks GTK to
+ resize it "immediately". This is needed because desktops like
+ GNOME shell otherwise won't allow resizing child frames at all.
+ (2) Do not try to synchronize the position of a child frame
+ after moving it. Needed because the present implementation
+ introduces a 0.5 secs delay which makes dragging child frames
+ virtually impossible with Lucid and Motif toolkits on desktops
+ like GNOME shell that use invisible outer frame borders.
+
+ For further information see the thread starting with
+ https://lists.gnu.org/archive/html/emacs-devel/2020-01/msg00343.html
+
+ * src/frame.c (syms_of_frame): New symbol Qxg_frame_set_char_size_4.
+ * src/gtkutil.c (xg_frame_set_char_size): Hide child frame
+ during resizing when 'x-gtk-resize-child-frames' equals 'hide'.
+ * src/xfns.c (x_set_parent_frame, Fx_create_frame): Set
+ gtk_container_resize_mode to GTK_RESIZE_IMMEDIATE for child
+ frames when'x-gtk-resize-child-frames' equals 'resize-mode'.
+ (Fx_gtk_debug): New function to toggle interactive GTK debugging
+ from within Emacs.
+ (syms_of_xfns): New symbols Qhide and Qresize_mode.
+ (x-gtk-resize-child-frames): New option that allows to resize
+ child frames on desktops like GNOME shell (with the mutter WM)
+ that otherwise refuse to resize them.
+ * src/xterm.c (x_set_offset): Don't x_sync_with_move for child
+ frames, it makes moving child frames virtually impossible with
+ the Lucid and Motif toolkits.
+
+2020-04-05 Philipp Stephani <phst@google.com>
+
+ Fix syntax error in man page.
+
+ * doc/man/emacs.1.in: Fix syntax of --script argument. The Info

+
+ * lisp/emacs-lisp/re-builder.el (reb-while): Take the current value of

+ don't wrongly treat it as dynamicly bound.

+2020-04-03 Philipp Stephani <phst@google.com>
+
+ Fix small bug in copy_string_contents.
+
+ * src/emacs-module.c (module_copy_string_contents): Fix incorrect
+ variable use. In this branch 'lisp_str_utf8' is always nil, so it
+ makes little sense to add it as error data.
+
+2020-04-03 Eli Zaretskii <eliz@gnu.org>
+
+ Fix invocations of gpg from Gnus
+
+ * lisp/epg-config.el (epg-config--make-gpg-configuration): Bind

+ possible values of 'no-conversion' or somesuch by the callers.
+ (Bug#40248)
+
+2020-04-03 Martin Rudalics <rudalics@gmx.at>

+ Don't draw GTK's internal border and tab bar on top of each other

+
+2020-04-03 Amin Bandali <bandali@gnu.org>
+
+ Tweak htmlfontify's generated output
+
+ * lisp/htmlfontify.el (hfy-default-header): declare the character
+ encoding for the generated HTML file. This helps browsers display
+ UTF-8 characters like the copyright symbol correctly.
+ (hfy-sprintf-stylesheet): apply the default style to all of the text
+ consistently, so that unstyled bits (which are not wrapped in span
+ tags and are directly part of the surrounding pre tag's "innerHTML")
+ have a look consistent with the rest of the document.
+
+2020-03-30 Dmitry Gutov <dgutov@yandex.ru>

+ Make sure FILES is not empty.
+
+2020-03-30 Alan Mackenzie <acm@muc.de>
+
+ Let imenu to work on the menu bar when its list is a single non-nested member.
+
+ * lisp/imenu.el (imenu-update-menubar): No longer accept a list of length 1 as

+ Don't add repeated xlmns:xlink declarations in svg-create

+
+ Don't signal during backtrace unrewind (Bug#40088)
+
+ backtrace_eval_unrewind is used to temporarily reverse
+ let-bindings (it's called with a positive argument to reverse
+ bindings, and then a negative argument to re-apply them) by
+ backtrace--locals and backtrace-eval. For the SPECPDL_LET_DEFAULT and
+ SPECPDL_LET_LOCAL cases (which occur for let-bindings on buffer-local
+ variables), the code calls Fdefault_value and Fbuffer_local_value on
+ the symbol.
+
+ For symbols which are unbound at top-level, the first (with positive
+ argument) call to backtrace_eval_unrewind will set the symbol's value
+ to unbound (putting the current value in the specpdl's "old value"
+ slot). On the second (with negative argument) call,
+ backtrace_eval_unrewind attempts to retrieve the symbol's value with
+ Fdefault_value or Fbuffer_local_value, but that raises a void-variable
+ signal. This interrupts the restoration of the let-bindings, so any
+ other variables more recent on the stack will now have the wrong
+ value.
+
+ * src/data.c (default_value): Make non-static.
+ * src/lisp.h: Declare it.
+ * src/eval.c (backtrace_eval_unrewind): Replace the calls to
+ Fdefault_value and Fbuffer_local_value with default_value and
+ buffer_local_value, respectively. The latter do exactly the same as
+ the former, except if the symbol's value is Qunbound they just return
+ it instead of signaling void-variable.
+
+2020-03-23 Noam Postavsky <npostavs@gmail.com>
+
+ Fix a couple of problems in changelog generating functions
+
+ * lisp/vc/diff-mode.el (diff-add-log-current-defuns): If there is a

+ easily happen since we are calling end-of-defun on a partial code
+ fragment from a diff.
+ * lisp/vc/log-edit.el (log-edit-generate-changelog-from-diff): Bind
+ display-buffer-overriding-action around the log-edit-show-diff call
