* src/xterm.c (x_dnd_get_target_window): Set proto_out even if
it won't be used because target is None. Reported by Lars
Ingebrigtsen <larsi@gnus.org>.

selection targets for the benefit of Qt and Mozilla.
* lisp/select.el (xselect--encode-string)
(selection-converter-alist): Add new selection targets.
* src/xterm.c (x_dnd_get_window_proxy): New function.
(x_dnd_get_target_window): New argument proto_out, and return
first window with XdndAware instead of bottommost window.
(handle_one_xevent): Use new argument `proto_out'.
* doc/lispref/frames.texi (Drag and Drop): Document new
parameter `return-frame' to `x-begin-drag'.

feature.

return_frame_p.
(handle_one_xevent): Set new flags and return frame whenever
appropriate.
* src/xterm.h: Update prototypes.
This still probably needs some more protection from
malfunctioning clients which delete windows at random, but I
don't know if that's a problem in practice.
* doc/emacs/frames.texi (Drag and Drop):
* doc/lispref/frames.texi (Drag and Drop): Document new
features.

option `mouse-drag-and-drop-region-cross-program'.

user option.

frame, begin a window system drag.

code.

indentation of opening paren.

drag-and-drop.

(syms_of_xterm): New symbol QXdndSelection.
* src/xterm.h (struct x_display_info): New atoms
Xatom_XdndAware, Xatom_XdndSelection, Xatom_XdndTypeList,
Xatom_XdndActionCopy, Xatom_XdndActionMove,
Xatom_XdndActionLink, Xatom_XdndActionAsk,
Xatom_XdndActionPrivate, Xatom_XdndActionList,
Xatom_XdndActionDescription, Xatom_XdndProxy, Xatom_XdndEnter,
Xatom_XdndPosition, Xatom_XdndStatus, Xatom_XdndLeave,
Xatom_XdndDrop, and Xatom_XdndFinished.
* lisp/textmodes/tex-mode.el (doctex-syntax-propertize-rules):
Add support for the new ^^X and consider the first ^ of ^^A to be the
closing char for the previous comment.
(doctex-font-lock-^^A): Simplify accordingly.
This should be better in the long run.

eliminating the goto it introduced.

* lisp/gnus-sum.el (gnus-collect-urls-from-article): New function,
extracted from `gnus-summary-browse-url'.
(gnus-summary-browse-url): Use it; also use `browse-url-button-open-url'
to handle the prefix argument.
(gnus-summary-browse-all-urls): New command.
(gnus-summary-mode-map): Bind `gnus-summary-browse-all-urls' to "v".
For example, 'xref-item' uses the list form of ':noinline'.

* src/haiku_support.cc (class EmacsScrollBar): New field
`maybe_overscroll'.

(MouseMoved): Also test `maybe_overscroll' to ensure that a grab
started inside the scroll bar.
* lisp/eshell/em-pred.el (eshell-add-pred-func): Let-bind 'pred' so
the lambdas see the original value (bug#54369).
Committed on the wrong branch.
Do not merge to master.
Use a dedicated stack for bytecode, instead of using the C stack.
Stack frames are managed explicitly and we stay in the same
exec_byte_code activation throughout bytecode function calls and
returns. In other words, exec_byte_code no longer uses recursion
for calling bytecode functions.
This results in better performance, and bytecode recursion is no
longer limited by the size of the C stack. The bytecode stack is
currently of fixed size but overflow is handled gracefully by
signalling a Lisp error instead of the hard crash that we get now.
In addition, GC marking of the stack is now faster and more precise.
Full precision could be attained if desired.
