-	* 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.
