I fixed those.

Done.

Not sure what example you had in mind.  The text mentions 3 profiler
commands to invoke, and describes the resulting profile.  What would
the example include, besides just "M-x profile-start" etc., which
sounds redundant?

> Also, some brief comparison of profile, elp, and benchmark could be helpful: what are their particular purposes, strengths, etc.

I think this was already clear from the text: e.g., benchmark only
measures the total execution time of a form, it doesn't produce any
insights on the distribution of that time between the form's
components.  I added more text to make some differences more clear.

Thanks.
