On the other hand, that work has a lousy bus factor.  Here is the first
page of recent commits on GUILE's master branch:

character.

Emacs's master branch looks a bit more diverse in authorship and less
back-and-forth in content.

Even if I only look at lisp/emacs-lisp/byte-compile.el (since it would
be unfair to take all of Emacs, a diverse application pool, as
comparison to a language):

Paul Eggert Fix a few problems with directed quotes
Paul Eggert Backslash cleanup in Elisp source files
Paul Eggert Revert some stray curved quotes I missed earlier
Paul Eggert Go back to grave quoting in source-code docstrings etc.
Stefan Monnier Fix disassembly of non-compiled lexical functions (bug#21377)
Paul Eggert Treat “instead” strings as docstrings
Paul Eggert Prefer directed to neutral quotes
Paul Eggert More-conservative ‘format’ quote restyling
Paul Eggert text-quoting-style in emacs-lisp diagnostics
Glenn Morris Address a compilation warning.
