And then I noticed that the original strings had \n at the end.  By
adding that, the first variant works (help inside of Emacs in a separate
buffer).  If I get help on a command I already got htmlhelp for I see
the old text buffer; ordinarily that would be the right thing to do.  In
my case I see
Warning message:
In help("intervals", htmlhelp = TRUE) :
  htmhelp = TRUE is deprecated: use help_type ="html"
Killing the old buffer cleans things up.

That still leaves the problem of how to make the setting persistent so I
don't need to set the variable each session.  I'm not sure if the
previous thread on help implies I can set something in .Rprofile or not.
