Re: @key broken

[Karl Berry]

    In the printed manual, this looks like
      \r
      \R
      \RET
      \s
      \S
      \SP

Ah.  Ok, I see the issue now for groff, but exceedingly few programs
need to document anything about \ANY-ARBITARY-KEY.  Whereas the angle
brackets, backslashes, lozenges, or whatever, just seem like a
distraction when there is no practical confusion.

So maybe you could/should hack up another macro for groff.texinfo to
insert the angle brackets (or whatever you prefer)?

Alternatively, if you want a style option in texinfo.tex, I don't mind.
I'm believing more than ever that the default should be unchanged,
though.
