This reverts this change:

  Author:     Andreas Schwab 
  AuthorDate: Sun Feb 8 12:34:02 2026 +0100

    Extend emacs server protocol for empty arguments

    An empty argument is represented by &0.  On the receiving side, &0 is
    replaced by nothing.

    * lisp/server.el (server-unquote-arg): Replace "&0" by nothing.
    (server-quote-arg): Produce "&0" for an empty string.
    * lib-src/emacsclient.c (quote_argument): Produce "&0" for an
    empty string.
    (unquote_argument): Replace "&0" by nothing.   (Bug#80356)

The bug in question was already fixed by this change:

    string arguments from emacsclient.

make-docfile preferring streq

2025-12-14T22:47:22+00:00

* lib-src/make-docfile.c (main, add_global, compare_globals):
Prefer streq to strcmp where either will do.

Support nested parens in make-docfile args

2025-12-14T22:47:21+00:00

* lib-src/make-docfile.c (scan_c_stream): Allow nested parens.
E.g., ‘(Lisp_Object XXX (force))’ for the identifier ‘force’,
where XXX is a macro.  This is for future changes.

Fix make-docfile strncmp typo

2025-12-14T22:47:21+00:00

* lib-src/make-docfile.c (write_c_args):
Don’t mishandle the identifiers ‘v’, ‘vo’, and ‘voi’.

Improve make-docfile.c for C23

2025-12-14T22:47:21+00:00

* lib-src/make-docfile.c (write_c_args): Don’t diagnose “()”.
In C23 it’s equivalent to (void), and it works fine (albeit with
less type-checking) in older C.  Omit first arg, which is no
longer needed.  Caller changed.

Fix some make-docfile core dumps

2025-12-14T22:47:21+00:00

This bit me when I ran ‘make’ with typos in the Emacs source.
* lib-src/make-docfile.c (struct rcsoc_state.buf_lim):
New member.
(read_c_string_or_comment): Initialize it.
(put_char, scan_c_stream): Check for buffer overflow.
(scan_c_stream): Output a diagnostic rather than aborting
when the buffer overflows.
