This the timing lines after the text source is just aligned to the
longest line, so it looks like this:

	ruby 2.2.0dev (2014-02-28 trunk 45211) [x86_64-linux]   0.071003417
	built-ruby                                              0.0817603

Execution time summary header isn't changed, but the times themselves
look much better:

	Execution time (sec)
	name	ruby 2.2.0dev (2014-02-28 trunk 45211) [x86_64-linux]	built-ruby
	app_answer                         0.071    0.082
	app_aobench                       84.672   84.014
	app_erb                            1.511    1.524

I didn't check the speedup ratio header, but maybe the "name\tbuilt-ruby"
looks a little odd.  I can fix that.  The first line
("compare with the result of") is unchanged (and too long, but I don't
read that).

	Speedup ratio: compare with the result of `ruby 2.2.0dev (2014-02-28 trunk 45211) [x86_64-linux]' (greater is better)
	name	built-ruby
	app_answer                         0.868
	app_aobench                        1.008
	app_erb                            0.992
