Description:
I want to be able to use code like "{{fullurl:{{subst:PAGENAME}}|diff=last&oldid={{subst:REVISIONID}}}}" to generate a diff of the current edit (same edit i enter that code in), but {{SUBST:REVISIONID}} comes up as blank.
See http://en.wikipedia.org/w/index.php?title=Wikipedia:Sandbox&diff=171246052&oldid=171245824
Version: unspecified
Severity: trivial

It's not clear if it should expand to the previous current revision, or the newly-saved one (the code i was trying to use assumes it is the newly-saved one) - maybe different keywords should be used for both.
Fundamentally you can't subst the revision id, as the revision id is not known until after the revision is recorded in the database.
Sorry!

What about a way to subst with the _current_ revision id (the one that already exists) - that might make less sense logically, but would allow for what I want to use it for.
Well, that would be pretty horrifyingly ugly IMHO. ;)
An additional problem is that a SUBST'ed revision ID would point to the wrong revision after certain types of operations, such as transferring a page between wikis. Since the correct value may change, subst seems inappropriate even if it did work.

One may use {{subst:fullurl:...|...{{subst:REVISIONID}}...}} so that the page can be transferred to other wikis.

Sorry, I'm wrong.
