RE: Editfiles convergence bug

[Andrews, Martin]

Special support for password entries seems wrong - though a relaxing of the
ReplaceAll might be in order. Also, I am interested in 
preserving some parts of the original line. There was a patch at one time
that allowed you to use matched sections from the regular expression in
replacement string. This would let you do preserve fields for the root entry
too - say:

  BeginGroupIfNoLineMatching "^root:<somepasswordhash>:"
    ReplaceAll "^root:[^:]*:(.*)" With "root:<somepasswordhash>:\1"
  EndGroup

What happend to that patch? Maybe not for this example, but I would like it
so I can add boot options to lilo.conf (or grub.conf) without wiping out
current boot options.
