bug#2000: rmail mode still broken

[jpff]

loaded a small RMAIL file and as it did not display labels I thought I
would try the headers (command h)

Debugger entered--Lisp error: (search-failed ",,")
  search-forward(",,")
  rmail-make-summary-line-1(1)
  rmail-make-summary-line(1)
  rmail-new-summary("All" (rmail-summary) nil)
  rmail-summary()
  call-interactively(rmail-summary nil nil)

So that makes rmail unusable for my world.  I have 18000 messages in
one file and keywords and header is important
