+;;; Directory tracking
+;;; ===========================================================================
+;;; This code provides the shell mode input sentinel
+;;;     SHELL-DIRECTORY-TRACKER
+;;; that tracks cd, pushd, and popd commands issued to the shell, and
+;;; changes the current directory of the shell buffer accordingly.
+;;;
+;;; This is basically a fragile hack, although it's more accurate than
+;;; the original version in shell.el. It has the following failings:
+;;; 1. It doesn't know about the cdpath shell variable.
+;;; 2. It only spots the first command in a command sequence. E.g., it will
+;;;    miss the cd in "ls; cd foo"
+;;; 3. More generally, any complex command (like ";" sequencing) is going to
+;;;    throw it. Otherwise, you'd have to build an entire shell interpreter in
+;;;    emacs lisp.  Failing that, there's no way to catch shell commands where
+;;;    cd's are buried inside conditional expressions, aliases, and so forth.
+;;;
+;;; The whole approach is a crock. Shell aliases mess it up. File sourcing
+;;; messes it up. You run other processes under the shell; these each have
+;;; separate working directories, and some have commands for manipulating
+;;; their w.d.'s (e.g., the lcd command in ftp). Some of these programs have
+;;; commands that do *not* effect the current w.d. at all, but look like they
+;;; do (e.g., the cd command in ftp).  In shells that allow you job
+;;; control, you can switch between jobs, all having different w.d.'s. So
+;;; simply saying %3 can shift your w.d..
+;;;
+;;; The solution is to relax, not stress out about it, and settle for
+;;; a hack that works pretty well in typical circumstances. Remember
+;;; that a half-assed solution is more in keeping with the spirit of Unix, 
+;;; anyway. Blech.
+;;;
+;;; One good hack not implemented here for users of programmable shells
+;;; is to program up the shell w.d. manipulation commands to output
+;;; a coded command sequence to the tty. Something like
+;;;     ESC | <cwd> |
+;;; where <cwd> is the new current working directory. Then trash the
+;;; directory tracking machinery currently used in this package, and
+;;; replace it with a process filter that watches for and strips out
+;;; these messages.
+
+;;; REGEXP is a regular expression. STR is a string. START is a fixnum.
+;;; Returns T if REGEXP matches STR where the match is anchored to start
+;;; at position START in STR. Sort of like LOOKING-AT for strings.
