asis patch

[Rob Hartill <ha...@ooo.lanl.gov>]

nobody moaned about my .asis patch, so will one of the CVS unchallenged
please add it. The CHANGES text to go with it is..

  mod_asis used to pass on a Location header that refered to a local
  URL to the client. This is bad for clients (which react differently)
  and unlikely to be the behaviour the user expected. Local redirects
  from .asis are now handled locally (by Apache).

here it is again...
