	shell-process-cd called before executing command in shell, but must

In GNU Emacs 23.4.1 (x86_64-pc-linux-gnu, GTK+ Version 2.24.10)
 of 2012-04-07 on trouble, modified by Debian

I found md function useful under Bash:

  md () { mkdir -p "$1" && cd "$1"; }

as it save duplicate directory name typing. I decide to teach Emacs understand
this keyword. Natural way to do so is to modify:

  (setq shell-cd-regexp "[cm]d")

But I explore that this setting does not teach Emacs follow into directory
(default-directory still not updated). After debugging functions in
'lisp/shell.el.gz' I found that 'shell-process-cd' call 'shell-cd' which call
'cd' which fail as I believe because 'cd' called before 'md' actually passed
to shell  (directory does not exist and 'cd' fail)...

I think shell mode need to wait some mark that command processed (like waiting
for prompt). This fix my bug report automatically.

(This bug report unfortunately got no response at the time.)

I was unable to reproduce this bug in Emacs 28.  Are you still seeing
this in recent Emacs versions?

More information was requested, but no response was given within a
month, so I'm closing this bug report.  If the problem still exists,
please respond to this email and we'll reopen the bug report.
