I don't see a variable for that "extra info" that comes
after the script name in some cases. For example, imagemap has to
have some reference to which map to use. Now I've argued that we
should use something other than a slash to delimit the "extra" from
the path to imagemap, but it doesn't matter. As long as the server
knows what to do, it can isolate the "extra" and stash it in an
environment variable. So ... what do we call that variable?
I'm thinking PATH_EXTRA. This is to compliment PATH_INFO,
PATH_TRANSLATED, and SCRIPT_NAME, none of which (I think) do what
I'm looking for. I suppose we could have the scripts parse PATH_INFO,
but isn't this something that the server should do?
