Summary: re-syntax.html probably should not refer to \g<0>
Initial Comment:
In discussing backreferences (\ number), re-syntax.html
includes this parenthetical comment:
(There is a group 0, which is the entire matched pattern,
but it can't be referenced with \0; instead, use \g<0>.)
The \g syntax is not supported in regex patterns (only in
replacement text for substitutions). Even if it was
supported, I can't imagine patterns could ever really
support \0 (you'd have infinite regress, right?). Anyway,
I suggest removing the parenthetical comment (\g is
documented in node104.html in the discussion of
re.sub).

Done; I've removed the aside in rev. 1.94 of libre.tex. Thanks!
