A couple lines tripped me up while reading through this document for the first time. This change aims to reword/rework these areas, so that they are clearer on the first read.
These highlight groups replace the old mechanism of setting: - {g,b}:terminal_focused_cursor_highlight - {g,b}:terminal_unfocused_cursor_highlight
With some spacing/indentation fixes. Helped by: @Pyrohh, @kopischke
