I'm wondering if the different syntax below could be simpler:

   $ perf probe add <probe>
   $ perf probe del <probe>
   $ perf probe show       

   $ perf probe list <line>
           ...       --vars[=<pattern>] [--externs] <probe>
           ...       --funcs[=<pattern>]

instead of respectively:

   $ perf probe --add=<probe>
   $ perf probe --del=<probe>
   $ perf probe [--list|-l]       

   $ perf probe [--line|-L] <line>
   $ perf probe -V <probe> [--externs] [--filter=<pattern>]
   $ perf probe --funcs
