-Often tag names are redundant; this happens when the name of a tag is an
-easily guessable substring of the tag pattern. We define a set of rules
-to decide whether it is possible to deduce the tag name from the pattern,
-and make an unnamed tag in those cases. The name deduced from the
-pattern of an unnamed tag is the implicit name of that tag. The use of
-implicit tag names reduces the size of the tags file. When the user
-looks for a tag, and Emacs founds no explicit tag names that match it,
-Emacs then tries to match the tag with an implicit tag name. Such a
-match occurs when the tag matches a pattern, subject to the satisfaction
-of all the following four rules:
