This requires more typing than '**' is not near as expressive. The problem with
'*' is that it does not matches '/' which is the directory separator. So '**'
is just shorthand for the regular expression "([^/]*/)*".
Notice that on your your rule (3) there is no way to write a rule that only
takes one of this two files:
(a) a/b/c/CVS/d
(b) a/CVS/b/c/d
With '**' the rules are:
(a) **/CVS/*
(b) */CVS/**
It seems to have more expressive power.
