Build fails on Emacs 28.1

$ make
EMACS check-emacs-version
Using EMACS = emacs, version = 28.1
mkdir build-28.1
EMACS build-28.1/ghc-core.elc
EMACS build-28.1/ghci-script-mode.elc
EMACS build-28.1/haskell-align-imports.elc
EMACS build-28.1/haskell-c2hs.elc
EMACS build-28.1/haskell-cabal.elc

In toplevel form:
haskell-cabal.el:362:8: Error:  docstring wider than 80 characters
make: *** [Makefile:80: build-28.1/haskell-cabal.elc] エラー 1

Slightly off-topic, I have also found a problem with tests failing in environments without git. (Emacs 28.1)
The probability of this occurring is very low, but I am reporting it just in case.

Working on 28.1 now.
