* etc/NEWS: Announce the change. * src/dispextern.h (struct glyph_row): Add 'extra_line_spacing_above' member. (struct it): Add 'extra_line_spacing_above' member. * src/frame.h (struct frame): Add 'extra_line_spacing_above' member. Update comment for 'extra_line_spacing.' * src/buffer.c (syms_of_buffer): Update the docstring of 'line-spacing' to describe the cons cell usage. * src/buffer.h (struct buffer): Update comment for 'extra_line_spacing'. * src/frame.c (gui_set_line_spacing): Handle cons cell value for 'line-spacing'. Calculate and set 'extra_line_spacing_above' for both integer and float pairs. * src/xdisp.c (init_iterator): Initialize 'extra_line_spacing_above' from buffer or frame 'line-spacing', handling cons cells for both integer and float values. (gui_produce_glyphs): Use 'extra_line_spacing_above' to distribute spacing between ascent and descent. Update 'max_extra_line_spacing' calculation. (resize_mini_window): Take line spacing into account when resizing the mini window. Pass height of a single line to 'grow_mini_window' and 'shrink_mini_window'. * src/window.c (grow_mini_window, shrink_mini_window): Add unit argument which defines height of a single line. * src/window.h (grow_mini_window, shrink_mini_window): Adjust function prototypes accordingly with unit argument. * lisp/subr.el (total-line-spacing): New function to calculate total spacing from a number or cons cell. (posn-col-row): Use total-line-spacing. * lisp/simple.el (default-line-height): Use 'total-line-spacing'. * lisp/textmodes/picture.el (picture-mouse-set-point): Use 'total-line-spacing'. * lisp/window.el (window-default-line-height): Use 'total-line-spacing'. (window--resize-mini-window): Take 'line-spacing' into account. * test/lisp/subr-tests.el (total-line-spacing): New test. * test/src/buffer-tests.el (test-line-spacing): New test. * doc/emacs/display.texi (Display Custom): Document that 'line-spacing' can be a cons cell. (Line Height): Document the new cons cell format for 'line-spacing' to allow vertical centering.

README for the Emacs Lisp Reference Manual.
* This directory contains the texinfo source files for the Emacs Lisp
Reference Manual.
* Report bugs in the Lisp Manual (or in Emacs) using M-x report-emacs-bug.
To ask questions, use the help-gnu-emacs mailing list.
* The Emacs Lisp Reference Manual is quite large. It totals around
1100 pages in smallbook format; the info files total around 3.0 megabytes.
* You can format this manual for Info, for printing hardcopy using TeX,
or for HTML.
* You can buy nicely printed copies from the Free Software Foundation.
Buying a manual from the Free Software Foundation helps support our GNU
development work. See <https://shop.fsf.org/>.
(At time of writing, this manual is out of print.)
* The master file for formatting this manual for Tex is called 'elisp.texi'.
It contains @include commands to include all the chapters that make up
the manual.
* This distribution contains a Makefile that you can use with GNU Make.
** To make an Info file, you need to install Texinfo, then run 'make info'.
** Use 'make elisp.pdf' or 'make elisp.html' to create PDF or HTML versions.
