You could possibly hack something like this:
1) Add a space at the beginning:
:%s/^/ /
2) Match the first column
call matchadd('Conceal', '^ ')
3) change syntax highlighting for the conceal highlighting group
hi Conceal ctermbg=Red ctermfg=Red
You need to adjust the color to your taste and depending on whether
you use terminal vim or gvim, you need to use cterm(bg,fg) (for the former)
or gui(bg,fg) for the latter.
