The result of native compilation of fish-mode.el is :
Compiling /home/fred/.emacs.d/elpa/fish-mode-20210215.1114/fish-
mode.el...

In fish/count-tokens-on-current-line:
fish-mode.el:393:8: Warning: docstring wider than 80 characters

In fish/auto-indent-post-indent-check:
fish-mode.el:663:8: Warning: docstring wider than 80 characters
Compilation finished.

If I remove the corresponding docstrings in fish-mode.el, the warnings
disappears in *Async-native-compile-log* but the indentation remains
incorrect.

PS: in my first message, I compared 2 versions of Emacs 28.0.91
(compiled with or without native compilation enabled). We can also
hightlight the problem only using Emacs with native compilation enabled
: if we add "(setq load-no-native t)" in init.el, the indentation is
correct.
