I'm used grepping on the --debug output from client/mtt, which means e.g., I
will now see double the number of POSTGRES ERRORs. Isn't that confusing? At the
*end* of the mtt run, I'd much prefer to just say, e.g., "34 SQL errors
occured". If they want to see the actual SQL error messages from submit.php,
users can do:

$ client/mtt --debug ... | tee debug && grep -i POSTGRES debug

If submit.php?debug is used, the exact submission entry that caused the error(s)
can be traced.
