" Simple emulation of indentation guides.

" For tab-based indentation, using the 'listchars' option works fine.
" For space-based indentation, one can either:
" • use the match highlighting feature (see ':help match-highlight'),
"   as shown in ToggleMatchHighlightIndentGuides(); or
" • use the 'leadmultispace' setting of the 'listchars' option (added
"   in Vim 9.0), as shown in ToggleListCharsIndentGuides().
