[patch 0/5] perf stat --log-fd=N

[Jim Cromie]

hi Arnaldo,

Heres the "update" to the patchset I promised.

[PATCH 1/5] perf stat: add --log-fd <N> option to redirect stderr
[PATCH 2/5] perf-stat: fix +- nan% in --no-aggr runs
[PATCH 3/5] perf stat: suppress printing std-dev when its 0
[PATCH 4/5] perf stat: allow tab as cvs delimiter
[PATCH 5/5] perf stat: fix spelling in comment

Ive dropped the 'print-ops' patches for a few reasons:

- pretty and cvs outputs have diverged further, pretty has added info,
  cvs has dropped the final timing line (probably cuz it didnt fit in
  the table). I presume there are good reasons for this.

- Id be parsing with perl anyway, so cvs regularity isnt important, and
  the richer info in pretty mode is useful.

- fiddling with output format is just as likely to break somebodys parsing,
  minor aesthetic improvements arent worth it. Its easier to do nothing.
