Draw spaces, tabs, newlines and nbsp.
Via gsettings it is possible to enable the drawing of:
- newline (enable-space-drawer-newline)
- spaces (enable-space-drawer-space)
- tab (enable-space-drawer-tab)
- not blank space (enable-space-drawer-nbsp)
The first setting is a boolean ones, so the only allowable values
are true (show the symbol) or false (don't show the symbol).
Instead for the last three settings, the allowed values are:
'draw-none' -> show nothing
'draw-all' -> show all spaces/tabs
'draw-trailing' -> show only the trailing spaces/tabs (only if GTK >= 3.24)
