Subject: [PATCH 3.16 169/233] perf script python: Remove dups in
 documentation examples

3.16.48-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: SeongJae Park <sj38.park@...il.com>

commit 14fc42fa1b3e7ea5160c84d0e686a3a0c1ffe619 upstream.

Few shell command examples in perf-script-python.txt has few nitpicks
include:

- tools/perf/scripts/python directory listing command is unnecessarily
  repeated.
- few examples contain additional information in command prompt
  unnecessarily and inconsistently.

This commit fixes them to enhance readability of the document.
