* lisp/files.el (dir-locals-read-from-dir): Handle syntactically
invalid .dir-locals.el files more gently (bug#48568). Give a
message instead of bugging out later.
* lisp/files.el (move-file-to-trash): Pass the correct dir-flag to
make-temp-file so that a directory is created when a directory is
being trashed (Bug#47960).
* lisp/files.el (hack-local-variables): Fix the ordering which
local variables are evaluated by `hack-local-variables' so that
prop-line local variables are evaluated first. There is a hidden
nreverse lurking in `hack-local-variables-apply' which means that
the prop line variables must come second in order to be evaluated
before the end of file variables.
* doc/lispref/backups.texi (Auto-Saving): Explain UNIQUIFY being a
secure hash in auto-save-file-name-transforms.
* etc/NEWS: Mention change in `auto-save-file-name-transforms'.
* lisp/files.el (auto-save-file-name-transforms): Adapt docstring.
(make-auto-save-file-name): Care, if UNIQ is a secure hash symbol.
* doc/lispref/variables.texi (File Local Variables): Document
`permanently-enabled-local-variables'.
* lisp/files.el (enable-local-variables): Mention the new variable.
(set-auto-mode): Always call `hack-local-variables'.
(hack-local-variables): Factor out the variable gathering into its
own function, and respect the new variable (bug#47843).
(hack-local-variables--find-variables): Factored out from
`hack-local-variables'.
(permanently-enabled-local-variables): New variable.
* lisp/files.el (file-name-non-special): Do not expand `file-truename'.
* lisp/net/tramp-sh.el (tramp-do-copy-or-rename-file-out-of-band):
Use local `default-directory' for `start-process'.
* lisp/files.el (files--ask-user-about-large-file-help-text): New
function that returns information about opening large files in
Emacs. (Bug#45412)
(files--ask-user-about-large-file): Use read-multiple-choice to
display the available actions.
* etc/NEWS: Advertise the new feature.
* lisp/files.el (after-find-file): Behave the same in when
warning/not warning (bug#47850). This fixes this test case:
(switch-to-buffer (find-file-noselect "non-existing-dir/test.el" t))
which would leave the buffer read-only.
* lisp/files.el (move-file-to-trash): Allow moving files to trash
even if there's a file in trash with the same name (but no entry
in info) (bug#47135).
Use newer primitives like file-accessible-directory-p to simplify
and speed up longstanding code in after-find-file.
* lisp/files.el (after-find-file):
Prefer file-exists-p + file-symlink-p to file-attributes +
file-symlink-p + file-chase-links + file-exists-p.
Prefer file-accessible-directory-p to directory-file-name +
file-attributes.
Prefer file-directory-p to file-name-directory + file-exists-p.
* lisp/files.el (dir-locals-collect-variables): Compare directory
names after expanding. This makes a (subdirs . nil) in ~/ work as
expected (bug#17205).
Test case:
((nil . ((a . "hallo")
(subdirs . nil))))
in ~/
* lisp/files.el (dir-locals-collect-variables): Don't
destructively modify the cached structure (bug#17205), because
that means that (subdirs . nil) doesn't work.
* lisp/subr.el (read-char-choice-use-read-key): New variable.
(read-char-choice): Use read-char-from-minibuffer when
read-char-choice-use-read-key is nil.
(y-or-n-p-use-read-key): New variable.
(y-or-n-p): Restore old code that calls read-key to use it when
y-or-n-p-use-read-key is non-nil.
* lisp/dired-aux.el (dired--no-subst-ask, dired-query):
* lisp/files.el (files--ask-user-about-large-file)
(hack-local-variables-confirm):
* lisp/userlock.el (ask-user-about-supersession-threat):
* lisp/wid-edit.el (widget-choose): Revert to use read-char-choice
instead of read-char-from-minibuffer.

Give get-buffer-create an optional argument to inhibit buffer hooks

(Fmake_indirect_buffer, Frename_buffer, Fbury_buffer_internal)
(record_buffer): Use run_buffer_list_update_hook.

since it is no longer needed in src/buffer.c.
(code_conversion_restore, code_conversion_save, syms_of_coding):
Prefer boolean over integer constants.
* src/fileio.c (Finsert_file_contents): Inhibit buffer hooks in
