>Description:
Shouldn't this paragraph in BUGS section in manual page of re_format:

     Back references are a dreadful botch, posing major problems for efficient
     implementations.  They are also somewhat vaguely defined (does
     `a\(\(b\)*\2\)*d' match `abbbd'?).  Avoid using them.

     Back references are a dreadful botch, posing major problems for efficient
     implementations.  They are also somewhat vaguely defined (does
     `a((b)*\2)*d' match `abbbd'?).  Avoid using them.

because `a\(\(b\)*\2\)*d' is in obsolete notation? Or does this bug concern only the obsolete REs?
