* doc/emacs/frames.texi (Menu Mouse Clicks): Describe context-menu-mode
and context-menu-functions instead of suggesting global-set-key.
(Menu Bars): Mention context-menu-mode and context-menu-functions.

* etc/NEWS: Add context-menu-mode and context-menu-functions.

* lisp/mouse.el (context-menu-functions): Use :type with repeat/function-item.
(context-menu-minor, context-menu-undo, context-menu-region)
(context-menu-ffap): Improve docstrings displayed for function-item in
defcustom of context-menu-functions.

(Recursive Editing): Document throwing of function values to `exit'.

* doc/lispref/errors.texi (Standard Errors): Document
`minibuffer-quit'

* lisp/minibuffer.el (minibuffer-quit-recursive-edit): New function.

* lisp/simple.el (minibuffer-error-function): Do not abort keyboard
macro execution if is minibuffer-quit is signaled (bug#48603).
* src/data.c (syms_of_data): New error symbol `minibuffer-quit'

* src/keyboard.c (recursive_edit_1): Implement throwing of function
values to `exit`.  In that case, the function will be called without
arguments before returning from the command loop.
(cmd_error):
(Fcommand_error_default_function): Do not abort keyboard macro
execution if minibuffer-quit is signaled.
(command_loop_2): New argument HANDLERS.

* lisp/replace.el:
Add the commands 'kill-matching-lines' and 'copy-matching-lines'.

'kill-matching-lines' is like 'flush-lines', but adds the lines to the
kill ring as a single string, keeping line endings.
'copy-matching-lines' is like 'kill-matching-lines', but only copies
those lines instead of killing them.

* doc/lispref/eval.texi (Function Indirection): Make example more
robust (bug#49647).  Suggested by Scott Marks
<scott.c.marks@gmail.com>.

* src/buffer.c (Fmake_indirect_buffer): Fix a typo in a recent
change.

* doc/lispref/buffers.texi (Indirect Buffers): Fix punctuation.

to inhibit buffer hooks.

* doc/emacs/misc.texi (Shell Mode): Document the new optional
behavior of 'C-c C-o'.

* etc/NEWS: Call out the new behavior of 'C-c C-o'.

* doc/lispref/hooks.texi (Standard Hooks): Ditto.

* src/callint.c (syms_of_callint): Document the actual usage of
`mouse-leave-buffer-hook' (bug#2932).
