Just checked it out. It's a significant improvement, thank you.

Two notes:

- I have 'C-h C-a' rebound to 'apropos' instead of 'apropos-command' 
locally. As a result, help-for-help shows 'M-x apropos-commnad' in the 
first column and (see also 'a') later.

The regression is that the previous version printed

  M-x apropos-command PATTERN

followed by 3 spaces, whereas the new one prints
  M-x apropos-commandTABSearch for commands (see also a)

and for some reason TAB is printed with zero width.

It's a minor thing, to be honest.

- Not a regression, old problem:

Instructions say "Type ..., or SPC or DEL to scroll".

But DEL here is actually <backspace>. If I just press Delete on the 
keyboard, help-for-help exits instead of scrolling.

And the target audience of help-for-help is probably at least as 
ignorant as myself about the difference between DEL and Delete.

Perhaps the easiest fix would be to handle Delete same as Backspace here.
