Patrick Palka 914966e499 contrib/vimrc: detect more C-like files
Currently this script doesn't set the indentation style for the standard
library headers under libstdc++/ because they lack a file extension.
But they do have a modeline, so the file type is still set appropriately
by Vim.  So by inspecting &filetype, we can also detect these standard
library headers as C-like files.

contrib/ChangeLog:

	* vimrc (SetStyle): Also inspect &filetype to determine whether
	a file is C-like.

" Code formatting settings for Vim.

" To enable this for GCC files by default, you can either source this file
" in your .vimrc via autocmd:
" :au BufNewFile,BufReadPost path/to/gcc/* :so path/to/gcc/contrib/vimrc
" or source the script manually for each newly opened file:
" :so contrib/vimrc
" You could also use numerous plugins that enable local vimrc e.g.
" mbr's localvimrc or thinca's vim-localrc (but note that the latter
" is much less secure). To install local vimrc config, run
" $ make vimrc
" from GCC build folder.
