We should verify whether we're looking for orphaned handlers or orphaned
calls. If it's handlers I'd do something like:
Scan all scripts for "end" & space to get a list of handlers
Remove duplicates
Scan all scripts for each handler name and keep a count
If there's only two instances of the handler name, it's an orphan.

There are many reasons to resort to "do" only after all other more
with-the-grain approaches cannot be made to work.
That it eludes static code analysis is just one more.
If I get around to tidying up my old orphan-finder and adding it to
other code base management tools in devolution, I wouldn't bother
attempting to handle "do" cases. Low ROI, and not handling them helps
draw attention to the technical debt many uses of "do" accrue.
Somewhat similar problem with "send" and "dispatch" commands as well.
You can alleviate this a bit during parsing by seeing if what follows
the "do" or "send" or "dispatch [function]" command is a quoted string.
