Title:
  'man perf-stat' has bad notation for specifying multiple events of
  interest

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  The SYNOPSIS in the manpage of perf-stat(1) says:

     perf stat [-e <EVENT> | --event=EVENT] [-a] <command>

  where -e specifies events of interest:

         -e, --event=
             Select the PMU event. Selection can be a symbolic event name (use perf list to list all events) or a raw PMU event 
             (eventsel+umask) in the form of rNNN where NNN is a hexadecimal event descriptor.

  Nowhere in the manpage does it say how to specify multiple events, or
  even whether that is possible. A strict reading of the syntax would
  suggest that it actually *isn't* possible.

  Now, it's not hard to guess: either 'perf -e event1 -e event2 ...' or
  'perf -e event1,event2' seems to work, but this should be specified
  explicitly. Perhaps something like

         -e, --event=
             Select the PMU event. Selection can be a symbolic event name (use perf list to list all events) or a raw PMU event 
             (eventsel+umask) in the form of rNNN where NNN is a hexadecimal event descriptor. Multiple events can be specified
             either as a comma-separated list or as multiple -e <EVENT> options.
