Re: dabbrev-completion doc string

[Richard M. Stallman]

    The last sentence of the doc string should be removed, IMO:

      "With no prefix argument, it reuses an old completion list
       if there is a suitable one already."

Thanks for pointing this out.  I will clarify it as follows to explain
the user-level consequences.


With no prefix argument, it reuses an old completion list
if there is a suitable one already.  This means that the
list of completions may not be entirely up to date
respect to the latest buffer contents."
