bug#6965: 23.2; tags search/replace order no longer sensitive to starting file

["Daniel B." <dsb@smart.net>]

The order in which tags tables files are searched is broken (relative
to previous versions of Emacs and the current documentation):

It no longer is sensitive to the starting file, as specified in the
info documentation (32.2.6):

   These commands scan the list of tags tables starting with the first
   tags table (if any) that describes the current file, proceed from there
   to the end of the list, and then scan from the beginning of the list
   until they have covered all the tables in the list."

That is, if you have a tags file for dir1/... and a tags file for
dir2/... and load both using visit-tags-table and choose to add to the
current list (rather than replacing), then starting a tags-search from
a file dir2/f should start searching per the tags table file for
dir2/..., and starting from a file dir1/f should start searching per the
tags file for dir1/....

However, Emacs 23.2 seems to always start with the same tags table file,
regardless of which file is the current file.
