Global variables override by buffer variables (#80)

[rockandska]

Hi,

Not a vim expert but seems to do the job requested by #80 and had personally the same needs.

It should allow users to be able to :

• enable/disable indent-guides at the buffer level
• tweak indent-guides at filetype / buffer level

For example, if you want :

• only tab indentation inside sh files
• only enable/show indent-guides for sh files

$ cat vimrc
let g:indent_guides_enable_on_vim_startup = 0
let g:indent_guides_tab_guides = 0
let g:indent_guides_space_guides = 1
let g:indent_guides_soft_pattern = ' '

$ cat after/ftplugin/sh.vim 
setlocal noexpandtab
setlocal softtabstop=0
setlocal shiftwidth=4
setlocal tabstop=4

let b:indent_guides_enable_on_vim_startup=1
let b:indent_guides_tab_guides = 1  
let b:indent_guides_space_guides = 0
let b:indent_guides_soft_pattern = '\t'

If you want enable indent-guides for all filetype / buffers except for sh filetype

$ cat vimrc
let g:indent_guides_enable_on_vim_startup = 1

$ cat after/ftplugin/sh.vim 
let b:indent_guides_enable_on_vim_startup=0

Comments / suggestions welcome
