159d392427 runtime(java): Complement the recognition of type parameter sections
In addition to matching type parameter sections of generic
classes and records and interfaces, match such sections of
generic methods and constructors.  As before, opt for it by
defining "g:java_highlight_generics"; the diamond form still
does not qualify for this kind of recognition.

And make section patterns agree with one another in syntax
items.

beb02ed674 runtime(java): Optionally highlight parameterised types
In the presence of parameterised types whose names begin
with a capital letter and end with a less-than sign "<" that
introduces a type argument or a list of comma-separated type
arguments, followed by a greater-than sign ">", a variable
"g:java_highlight_generics" can be defined to have some
components of such types uniformly coloured (by picking
highlight groups for javaGenericsC{1,2}, javaWildcardBound).

For example,
------------------------------------------------------------
java.io.InputStream stream = java.io.InputStream.nullInputStream();
java.util.function.Function<String,
    java.util.function.BiFunction<String, String, String>> updater =
	property -> (oldValue, newValue) -> oldValue;
java.util.logging.LogManager.getLogManager()
    .updateConfiguration(stream, updater);
------------------------------------------------------------

Note that the diamond form and explicit type arguments do
not qualify for this kind of recognition.

For example,
------------------------------------------------------------
new java.util.HashSet<>().<String>toArray(new String[0]);
------------------------------------------------------------
