tests: avoid nested quoting on command line for portability

Before this patch, test-revset.t fails on Solaris using ksh as default
"sh", because nested quoting below isn't acceptable for it.

                +-----------------------------+ inner quoting
    "`python -c "print '|'.join(['0:1'] * 500)"`"
    +-------------------------------------------+ outer quoting

This patch does below for portability.

  - omit outer quoting

    This should be safe, because generated string contains no white
    space character.

  - use '+' instead of '|' (for safety)

    '|' has special meaning for many shell, but '+' isn't (at least,
    for ordinary ones).

def testdispatch(cmd):
    """Simple wrapper around dispatch.dispatch()

    Prints command and result value, but does not handle quoting.
    """
    print "running: %s" % (cmd,)
    req = dispatch.request(cmd.split())
    result = dispatch.dispatch(req)
    print "result: %r" % (result,)
