[p4] Offline reconciliation: what files need to be added?

[Marc Wensauer]

This KB article provides very useful information on how to reconcile
offline changes:

For my purposes though, I need to *query* what needs to happen before
actually doing it.  For the most part, it's trivial to see what files
will have to opened for delete and edit via 'p4 diff -sd' and 'p4 diff
-se' respectively.

But how do I query my workspace for files that *would* have to be added?
 The 'find . -type f | p4 -x - add' recommendation is rather
brute-force, and doesn't avoid actually performing the operation instead
of just telling me about it.

How might one query for this information?  A recursive 'p4 files' and
grep for "no such file(s).", or is there something else I should
consider?

Thanks for your advice,
