Configuring indentation of commented license header in C++ file with vim/cindent

Question

I have a nice cindent configuration for my coding style, but the licence header of my file is reindented not correctly if i reindent all the file in vim.

the licence header :

/* =========================================================================

  Program:   Visualization Toolkit
  Module:    vtkPeriodicArray.txx

    PURPOSE.  See the above copyright notice for more information.

 ========================================================================= */

my .vimrc ( relevant section ):

:set tabstop=2    "Number of spaces a TAB in the text stands for  
:set shiftwidth=2 "Number of spaces used for each step of (auto)indent
:set expandtab
:set cindent
:set cinoptions={1s,t0,f0s,g0,i0,(0

Hoped results : no change in licence header indentation

Seen Results :

Answer 1

I have found a work around. I simply map the following command in my .vimrc :

map <F12> gg=G\|:3,12>\|:10,12> <Enter> <Enter>

It map the F12 key to :

• reindent all file
• indent line 3 to 12 of one indent
• indent line 10 to 12 of one indent

So it is very specific to my header and will not work in another project. All my vimrc is specific for this project anyway.
