Do not format the file if no Default formatprograms is found or the language is not supported

[c02y]

I just started to use vim-autoformat, and set au BufWrite * :Autoformat in my init file, and I found two issues:

1. If the language is supported but the formatprogram is not installed, vim will autoformat the file depending on the rules I don't know
2. If the language is not supported, vim will autoformat the file depending on the rules I don't know

Example:

1. When I edit ~/.config/sxhkd/sxhkdrc, the :set filetype? of it is markdown by my config(I use github space-vim config), but in README file, you said remark is supported for markdown, the thing is I don't get remark installed, so vim shouldn't autofomat it.
2. When I edit ~/.config/ranger/rc.conf, the :set filetype? of it is conf by my config, conf is not supported by vim-autoformat, so vim shouldn't format the buffer.

You can control this behavior with

let g:autoformat_autoindent = 0
let g:autoformat_retab = 0
let g:autoformat_remove_trailing_spaces = 0

as explained in the readme

Oh, I thought they are global variables that working for all buffers.

Thanks, it seems working.
