 Improved vim syntax highlighting for vim

 What it is

For a very long time I was not quite happy with the syntax
highlighting in vim for C code. That was until I met JC, a colleague
who had developped a much better syntax file which I quickly adopted
and installed on all my machines.

Unfortunately his work was based on an older vim version from 1998.
Today with the latest vim update, syntax was not working anymore. So
I finally took a deeper look about how this works, and extracted the
needed bits to make this a separate file that can be added to the
existing syntax, without having to redo everything.

 What it does

The main change is to detect and highlight types. The following cases
are detected:

  * Variable declarations
  * Functions return type
  * Function parameters (in declaration and definition)
  * C-style casts (not C++ ones yet, TODO)
  * C++ "new" operator

Another change is colorizing the parentheses of if, while, and for in
the same color as the keyword (but this overrides rainbow parentheses
so I'm not sure if it should be kept this way).

Ideally, other parts of the highlighting will be left unchanged, but
this part is not working perfectly yet.

 How to use it

Put c.vim and cpp.vim in your vim after/syntax/ directory. That's
all.

This script uses the standard colors for highlighting (mainly cType)
so you keep all your colorscheme and customizations when you install
it.

 How does it look

Here is a side by side comparison, with and without c.vim:

Of course it also works in C++ (and in non-dark mode):
