vim-patch:01a4fb1: runtime(java): Compose "g:java_highlight_signature" and "g:java_highlight_functions"
With the variables defined, distinctly highlight parts of
a method declaration header: its name and parameter list
parens, from its type parameters, return type, and formal
parameters; and distinctly highlight parts of a lambda
expression: its parameter list parens and the arrow, from
its formal parameters and identifiers.
