Also change window-tool-mode to not pay attention to if
tool-bar-map has a buffer local value or not as that made the
documentation complicated. Documentation added in Emacs manual,
Elisp manual, package commentary, and docstrings. Also extend
window-tool-bar support to Emacs 27 and newer. (bug#68765)

This directory contains source code for the parts of Emacs that are
written in Emacs Lisp. *.el files are Emacs Lisp source, and the
corresponding *.elc files are byte-compiled versions. Byte-compiled
files are architecture-independent.
The term subdirectory contains Lisp files that customize Emacs for
certain terminal types. When Emacs starts, it checks the TERM
environment variable to get the terminal type and loads
'term/${TERM}.el' if it exists.
The other subdirectories hold Lisp packages grouped by their general
purpose.
