bug#76307: [PATCH] Add 'project-forget-projects-under-dirs', limit dir selection to relevant dirs

[Ship Mints]

I tried your code to do a side-by-side but:

Debugger entered--Lisp error: (wrong-number-of-arguments read-directory-name 6)
  (read-directory-name prompt nil nil nil nil (let ((ps (mapcar #'(lambda (p) (expand-file-name ...)) project--list))) #'(lambda (dir) (catch 'ball (let ((tail ps)) (while tail (let ... ... ...)))))))

In any case, my approach produces all legitimate possibilities a user could want to clear projects under any common prefix, including "/" (which means forget everything), common prefixes for remote directories, common roots for multiple projects at the same level and common roots up the tree for projects that are in a deeper hierarchy.  This is effectively what I think people would want, and I assume you agree.  If your code produces the same and is more efficient, that's great.

I'm confused.  You can do those things in the current implementation,
and in my proposal too.

Could you perhaps spell out the benefit of your suggested implementation
for a concrete use case?  That might help to clear the confusion.


Thanks,
