Currently there is hard coded one character wide spacing around line 
numbers.
This patch adds `display-line-numbers-spacing-width' (default: 1),
which allows to configure the width of the spacing.
This is mostly motivated by wanting to set the spacing to zero.


This is result of make -C test:

I assume that failing c-ts-mode-test-indentation is unrelated to this patch.
