finishing Peter's fix of find_qn_bulk():

the new code used "if (update) ...",
while the function's signature read "... bit add ...";
this caused about 20 tests to fail with
"!ERROR: unknown variable 'update'."

fixed by renaming the parameter "add" to "update"
(the latter indeed seems more intuitive/descriptive than the former).

this makes the ~20 failing tests work, again.


Declaration/disclaimer:
-----------------------
On my FC6 desktop (64-bit, 64-bit OIDs, configured with --enable-optimize,
compiled with gcc 4.1.1), this check-in does not make any pathfinder test
fail that did not also fail with the most recent code base in CVS prior to
this check-in.
I did not check in detail, though, whether all previously failing tests
still fail the same way after this check-in as they did before this
check-in.
