Subject: [PATCH 2/7] perf record: Amend option summaries

From: Peter Zijlstra <peterz@...radead.org>

Because there's too many options and I cannot read, I frequently get
confused between -c and -P, and try to do things like:

  perf record -P 50000 -- foo

Which does not work; try and make the option description slightly longer
and hopefully less confusing.

[ Do those changes on the man page as well ]
