Indeed, that is not covered by the syntax rules for gitcommit [1]. You
can achieve this with additional syntax highlighting rules.
So here is the whole thing again with these additions:
---8<---
filetype plugin indent on
syntax on
hi def link gitcommitOverflow Error
autocmd BufEnter *
\ if &textwidth > 0 |
\ exec 'match Overlength /\%>' . &textwidth . 'v.\+/' |
\ endif
hi def link Overlength Error
" or customize it with other colors
"hi OverLength ctermbg=LightRed guibg=LightRed
--->8---
The '*' in the above autocmd is a wildcard match against the filename,
so if you want this for git only, replace it with COMMIT_EDITMSG.
