Thanks.  I didn't know that.  I don't think that's in the Elisp manual.

Also useful would be a command to expand "everything which is
sufficiently big" for some value of "sufficiently big", to avoid swathes
of irrelevancies down at 1% or 0%.

I once tried to amend the profiler to move its statistics columns
further to the right, because I was seeing far too many truncated
function names.  But I gave up, because the code was masses and masses
of tiny functions, largely without doc strings or comments, and I just
couldn't make sense of it.
