Re: \s[] gives syntax error (should restore previous size)

[Jim Avera]

Thanks for fixing the docs.

I'm curious, though, why \s can not support the no-argument form
in the same way that \f and \F do.

Ah, this is badly formulated in the info manual.  The groff(7) manpage
documents it correctly.

`\s' *always* needs an numeric argument.  So the valid forms to return
to the previous size are

   \s0
   \s(00
   \s[0]
   \s'0'

It's the `.ps' request which can be called without an argument.

Fixed in CVS, thanks.
