I just tried that:

static void on_document_open(GObject *obj, GeanyDocument *doc, gpointer 
user_data)
{
     if (doc != NULL)
         doc->changed=TRUE;
}

Two problems:

-When you go to close the document afterwards, it always says "The file 
'X' is not saved" which isn't quite true.  At least that confirms the 
above is being called, so I know my plug-in is working.

-Even though I've got that evidence the changed flag is being toggled, the 
menu structure doesn't seem to change.  Save and Save All are still 
disabled.

I'm not sure if those two discoveries mean that a plug-in based solution 
can't work for what I want here, or if I just need to make a much better 
one.

P.S. If someone feels like improving the "Plugin Signals" section of the 
documentation with a trivial edit, it would have made things easier if the 
sample on_document_open code snippet there included this addition:

   #include "document.h"

That's not already included in demoplugin.c, I had to add that in order to 
access the GeanyDocument structure.  The compiler error you get in that 
situation is a bit cryptic.
