SubjectRe: [PATCH 2/2] perf, tools: Support spark lines in perf stat
> fput could go into print_stat_spark

I wanted to keep the function generic, so that it can be easily
used in other places. Adding the space is somewhat specific
to stat.

Also the rest of the stat code has the white space printing
centralized in the caller too. I suppose makes it easier to change.

len is capped to NUM_SPARK_VALS, but the test needs to be on the
uncapped value. Otherwise exactly NUM_SPARK_VALS entries would
get a .. incorrectly.
