bug#27630: 26.0.50; Byte-compilation warnings in files.el

[Eli Zaretskii]

Compiling files.el produces the following 2 warnings:

  In create-file-buffer:
  files.el:1816:8:Warning: function create-file-buffer used to take 0+
      arguments, now takes 1

  In insert-directory:
  files.el:6595:43:Warning: function insert-directory used to take 0+ arguments,
      now takes 2-4

These warnings are meant to be emitted when a function's signature
changes, but in this case there's no change, so this seems to be a
bug.  The only hint I found as to why this happens is that both
functions appear in advice-add (insert-directory appears in advice-add
only on MS-Windows).
