The autofiles dpatch is (must be) listed last in 00list, so yes,
dpatch-edit-patch will apply all of the other patches to the temp tree
first.

The "set -e" and the initial trap is a trick to make sure that if the
command sequence fails for any reason, it'll exit with 230 rather than
with the exit code of the failed command.  This is so that
dpatch-edit-patch will know something went wrong.  I'm not sure why
dpatch-edit-patch doesn't consider any failure code a failure, but it
doesn't.  The final "trap - EXIT" clears the EXIT trap after we're
finished so we can exit normally.  Let me know if I didn't explain
that clearly enough.

Well, adding that should make it nearly impossible to end up with an
autofiles.dpatch that isn't "in sync" with all of the dpatches, but
practically speaking, it would also mean that every time you change or
add *any* dpatch, you'll have to run "debian/rules autofiles-sync".
Would that be too aggravating?  I'm not sure myself.
