run-tests: prevent a (glob) declaration from reordering (?) lines

Previously, if a series of optional output lines marked with '(?)' had a (glob)
in one of the first lines, the output would be reordered such that it came last
if none of the lines were output.  The (re) declaration wasn't affected, which
was helpful in figuring this out.  There were no tests for '(re) (?)' so add
that to make sure everything plays nice.

  $ hg init
  $ echo This is file a1 > a
  $ hg add a
  $ hg commit -m "commit #0"
  $ ls
  a
  $ echo This is file b1 > b
  $ hg add b
  $ hg commit -m "commit #1"
  $ hg co 0
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved

B should disappear

  $ ls
  a
