-        * etags.c: Use, together with etags.el, an optimised form of tags,
-        which are almost always unnamed.  etags.el looks for an explicit
-        tag name, then for an implicit one.  See make_tag for details.
-        The change is both forwards and backwards compatible.
+In short, the "optimised tags" are technically tags using "implicit tag
+names",
+
+        * etags.c: Implement implicit tag names, that is, unnamed tags
+        whose name is automatically deduced by etags.el.  The advantage is
+        that there is no explicit tag name in most tags, so the size of
+        the tags file is reduced, yet find-tag is able to do a match as
+        accurate as with named tags.  See the comment in make_tag for
+        details.
         (make_tag): New function (was the disabled function new_pfnote).
         (make_C_tag): Use it.
