TODO: <a href="https://golang.org/cl/343883">https://golang.org/cl/343883</a>: increase alternation precedence
The precedence of <code>/</code> in the argument for <code>-run</code> and
<code>-bench</code> has been increased. <code>A/B|C/D</code> used to be
treated as <code>A/(B|C)/D</code> and is now treated as
<code>(A/B)/(C/D)</code>.

TODO: <a href="https://golang.org/cl/356669">https://golang.org/cl/356669</a>: skip extra -count iterations if there are no tests
If the <code>-run</code> option does not select any tests, the
<code>-count</code> option is ignored. This could change the behavior of
existing tests in the unlikely case that a test changes the set of subtests
that are run each time the test function itself is run.
