Unfortunately I did not document the changes as I made them. I have been able to determine the purpose of most of the changes by code inspection but there are a few changes for which I have not been able to determine a purpose.
* Modifications to support XEmacs.
* Added the p4-lowlevel-locate-p4 function. This function is used to locate the p4 executable on the exec-path. It is used by the vc-p4-registered function to avoid an error on systems on which the Perforce client is not installed. This is useful if the same .emacs file is used on multiple systems, some of which do not have the Perforce client installed.
* Modified the p4-lowlevel-successful-alist-p function so that a command that returns the message "file(s) up-to-date" does not trigger an error. As part of this change I added the p4-lowlevel-ignore-error-list defcustom and the p4-lowlevel-should-ignore-error function.
* Modified the vc-p4-registered function so that it uses the p4-lowlevel-locate-p4 function to verify that the Perforce client is installed.

single request to the server in the simplest case (diff edited
file to synced version).
* p4-lowlevel.el (p4-lowlevel-command-into-buffer): Don't reorder
info and text lines.
(p4-lowlevel-diff): Support lists of files as well as a single file.

For vc-p4.el:
- delete a few more vc functions that are identical in emacs
- delete now unused vc-p4-change-times
- make vc-p4-annotate-command default to the internal elisp code
- delete vc-p4-state-heuristic, it's the same as the default
- new function vc-p4-find-version
- make a few functions cope with emacs-23 (not released yet),
that changes the first argument from FILE to FILE_LIST
- add an internal implementation for vc-annotate, simplify the
annotate code
For p4-lowlevel.el:
- fail graciously when offline and trying to access a file that
is under perforce
