--- Comment #1 from Wayne Sierke <> ---
A RE can be a literal of one or more characters. From re_format(7):

  A branch is one‡ or more pieces, concatenated.
  A piece is an atom possibly followed by a single‡ ‘*’, ‘+’, ‘?’, or
  An atom is ... , or a single character ...


  % echo foobar | awk -F o -v OFS=X '{$1=$1;print}'
  % echo foobar | awk -F oo -v OFS=X '{$1=$1;print}'

I don't think there is a need to separately reference single-character literal

(And unless I'm missing something I think the gawk man page is misguided for
doing so.)
