The find-file-noselect function uses two important subroutines which
are sometimes useful in user Lisp code: create-file-buffer and
after-find-file. This section explains how to use them.
This function creates a suitably named buffer for visiting filename, and returns it. It uses filename (sans directory) as the name if that name is free; otherwise, it appends a string such as ‘<2>’ to get an unused name. See also Creating Buffers.
Please note: create-file-buffer does not associate
the new buffer with a file and does not select the buffer. It also does not
use the default major mode.
(create-file-buffer "foo")
⇒ #<buffer foo>
(create-file-buffer "foo")
⇒ #<buffer foo<2>>
(create-file-buffer "foo")
⇒ #<buffer foo<3>>

This function is used by find-file-noselect. It uses
generate-new-buffer (voir la section Creating Buffers).
This function sets the buffer major mode, and parses local variables
(voir la section How Emacs Chooses a Major Mode). It is called by find-file-noselect and by
the default revert function (voir la section Reverting).
If reading the file got an error because the file does not exist, but its
directory does exist, the caller should pass a non-nil value for
error. In that case, after-find-file issues a warning:
‘(New file)’. For more serious errors, the caller should usually not
call after-find-file.
If warn is non-nil, then this function issues a warning if an
auto-save file exists and is more recent than the visited file.
If noauto is non-nil, that says not to enable or disable
Auto-Save mode. The mode remains enabled if it was enabled before.
If after-find-file-from-revert-buffer is non-nil, that means
this call was from revert-buffer. This has no direct effect, but
some mode functions and hook functions check the value of this variable.
If nomodes is non-nil, that means don't alter the buffer's
major mode, don't process local variables specifications in the file, and
don't run find-file-hook. This feature is used by
revert-buffer in some cases.
The last thing after-find-file does is call all the functions in the
list find-file-hook.
