Since I sent my previous message I noticed from the comment and the
code following the regexp, that "\\(\\[[0-9]+] \\)* is the only
possible interpretation.  The comment and code are _really_ looking
for a sequence of the type "[123] [3] ":

      ;; A good marker is one that:
      ;; 1) does not have a "[n] " prefix (not part of a stack backtrace)
      ;; 2) does have an "[n] " prefix and n is the lowest prefix seen
      ;;    since the last prompt

So I believe that we just should go ahead and change "\\(\[[0-9]+\] \\)*"
to "\\(\\[[0-9]+] \\)*".  I can do this, if desired.
