parentheses and brackets

[Werner LEMBERG]

For documenting groff, I need the following:

  @lparen{}
  @rparen{}
  @lbrack{}
  @rbrack{}

`(' and `)' create an `unbalanced parentheses message' in TeX (but not
in makeinfo, interestingly) in @deffn.

`[' and `]' produce brackets in the wrong font in @deffn.

Currently, I have to do this which is quite clumsy:

  @ifinfo
  @macro lparen
  [
  @end macro
  @end ifinfo

  @iftex
  @macro lparen
  @@lparen
  @end macro
  @end iftex
