* lisp/erc/erc.el (erc--switch-to-buffer): Commit
f925fc93ba "Add `predicate' arg to
`read-buffer' and use it for erc-iswitchb" meant to remove this, but
it was left behind. (Bug#53617)
Copyright-paperwork-exempt: yes
Functions on `completion-at-point-functions` should not modify
the buffer. Pcomplete itself mostly abides by this but Eshell's
use of it doesn't. Try and catch those cases. Also fix one of
those cases.
* lisp/pcomplete.el (pcomplete-allow-modifications): New var.
(pcomplete-completions-at-point): Enforce it.
(pcomplete, pcomplete-expand-and-complete, pcomplete-expand):
Rebind it since these commands expect the extra side effects.

selection converters.
(syms_of_xselect): Update doc strings.
The dependencies between `advice`, cl-generic`, `bytecomp`, `cl-lib`,
`simple`, `help`, ... were becoming unmanageable.
Break the reliance on `advice` (which includes making sure the
compiler is not needed during the early bootstrap).
* lisp/simple.el (pre-redisplay-function): Set without using `add-function`.
* lisp/loadup.el (advice, simple): Move to after `cl-generic`.

optimize during early-bootstrap.

`x-hide-tip' and `x-show-tip' directly.

`x-begin-drag' to match actual function arity.

variable.

the position of 'byte-run-strip-symbol-positions' in the eval-when-compile
entry. Add a call to `byte-run-strip-symbol-positions' in the
eval-and-compile entry.
There are custom entries that contain lambda's as values by default,
which can result in them containing embedded NULs after
byte-compilation, which wreaks havoc when they are saved to .emacs and
later read in. (Bug#52554)
* lisp/cus-edit.el (custom-save-all): Bind
print-escape-control-characters to t.
* lisp/startup.el (startup--load-user-init-file): Bind

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/lispref/frames.texi (Drag and Drop): Document new
features.

Add support for the new ^^X and consider the first ^ of ^^A to be the
closing char for the previous comment.
