Enable sign column auto toggle
Enable sign column auto toggle

Vim 8 introduced a new option to configure the state of the sign column
to be always visible ("yes"), always hidden ("no") or to automatically
toggle ("auto") when there are signs available to display.

This change is related to the warning message added to
"airblade/vim-gitgutter@dc73a81" which also advises to remove the custom
option "g:gitgutter_sign_column_always = 1" and use
"set signcolumn = auto" instead, described by the plugin owner in
"airblade/vim-gitgutter#431" "https://github.com/airblade/vim-gitgutter/issues/431#issuecomment-319696108).
