I asked this before, but apparently the documentation for this has not
been updated, as far as I can tell:

      Installed,

   You seem to have installed Jim's changes to search.c and regex.c, but
   not to searching.texi, nor, in as far as I can tell, to the NEWS.  As a
   result, the changes are, in as far as I can tell, completely undocumented.

   Is there a reason for that?
