Fix completely broken changes of 4 Feb 95 by brat@htilbom.ernet.in,
which were obviously never tested or even examined closely before
being installed.
(find-tag-file-order): Variable removed.
(find-tag-noselect): Remove gratuitously added variable SEARCH-TAG and
bogus clobbering of find-tag-order for patterns ending in dot (serious
braindamage here).
(find-tag-in-order): Remove gratuitously added variable TAGS-TABLE-FILE.
Remove variable MATCH-TYPE and code testing it for stupid special case.
(etags-recognize-tags-table): Put tag-exact-file-name-match-p first in
find-tag-tag-order list.  Don't set bogus find-tag-file-order variable.
(etags-snarf-tag): Notice file name match and return tag info with t
in place of tag text.
(etags-goto-tag-location): If (car TAG-INFO) is t, go directly to
the specified location.
(tag-exact-file-name-match-p): Renamed from tag-filename-match-p, and fixed.
(tags-table-files): Doc fix: names are returned unexpanded.
(etags-tags-table-files): Don't expand file names.
(tags-table-including, next-file): Expand result of (tags-table-files).
(tags-complete-tags-table-file): New function, helper for interactive
spec of list-tags.
(list-tags): Revert to original code, but use that function to lazify
the completion table.
(tags-list-functions-in-file, tags-locate-file-in-tags-table):
Functions removed.
