Oops, I should thought a bit more. Thanks for the clarification though.

I completely agree with you here, I just haven't found any useful
alternatives (re-defining the entire variable suffers from similar
problems to search/replace). Perhaps what I should have requested from the
beginning are more hooks to let plugins modify parts.

A problem as a designer of a plugin is that you have no feeling for what
you can expect to be added to the standard pmwiki (in order to support
your plugin. e.g. if you need a hook).

There is one problem with that though... the plugin won't work with old 
versions of pmwiki. This might not be such a big deal in practice though.

Let me ask for a specific hook: We (I and John) would like to add a button
to the edit page, how could we do this?  The button should probably be 
next to the 'save','preview' and 'reset' buttons. It'd be labelled 
something like "Delete draft" and it's purpose is hopefully self-evident.

PS. I hope I'm not completely off about adding a button, I think that was
the problem that caused me to initate this request.
