Thanks! Pushed.

BTW, do you have copyright assignment for Emacs?

I see an assignment on file for a person with the same name, but with a 
different email. Anyway, it's only important for any future patches.

Hi,

currently I am redifining `project-buffers' to ensure 'C-x p b'
(`project-switch-to-buffer') ignores some buffers I never want to switch to with 
that command:

(defvar mu-ignored-buffers
  '("\\` " "^\\*Async" "^\\*Completions" "^\\*Flymake" "^\\*Help"
    "^\\*Messages" "^\\*eldoc" "^\\*envrc" "\\*tramp" "^\\*vc" "^\\*xref")
  "A list of predicates for buffers to ignore.")

(cl-defmethod project-buffers ((project (head vc)))
  (let* ((root (expand-file-name (file-name-as-directory (project-root project))))
         (modules (unless (or (project--vc-merge-submodules-p root)
                              (project--submodule-p root))
                    (mapcar
                     (lambda (m) (format "%s%s/" root m))
                     (project--git-submodules))))
         dd
         bufs)
    (dolist (buf (buffer-list))
      (setq dd (expand-file-name (buffer-local-value 'default-directory buf)))
      (when (and (string-prefix-p root dd)
                 (not (cl-find-if (lambda (module) (string-prefix-p module dd))
                                  modules))
                 (not (seq-contains-p
                       mu-ignored-buffers (buffer-name buf) #'string-match-p)))
        (push buf bufs)))
    (nreverse bufs)))

I am not sure this is the best approach, though.

Would it be possible to add a defcustom to specify a predicate for the project 
buffers to be shown in `project-switch-to-buffer'?
