Thanks, too late. When I read your message, that commit was already
pushed oout. Sorry.

TABs are preferred, as they save  memory  footprint  for  the  U-Boot
image. But for the help textx, this often makes the code hard to read
and difficult to edit, so spaces are accepted here as well.

Long command names should be avoided  in  general.  If  the  name  is
exactly  8  characters,  so  that the '-' would align without a space
between the name and the '-', then omit it; otherwise add it.

Well, try and post them; probably on the next merge window.

Best regards,
