Sorry Tom, meant this to go to the list in the first place, hope you
don't mind my quoting your answer.

I don't see why my method would lead to more customisation. At the
moment, etags cannot replace the entries in TAGS for a given file. I
suggest adding this, so that we can call etags --replace index.php,
which will extract tags from index.php, and then replace index.php's
entry in TAGS with the tags found.

Sorry, by "file save" I really meant "file update", using inotify or
similar. Or maybe just an idle-timer-hook that checked the filemtimes.
