If you rename a directory via dired, buffers within that directory will
not also have their paths updated with the new directory.
Steps to reproduce:
1. Start "emacs -Q""
2. Evaluate the following:
(let* ((temp-dir (make-temp-file "dired_bug" t))
(subdir (expand-file-name "foo" temp-dir))
(a-file (expand-file-name "zzzz" subdir)))
(make-directory subdir)
(find-file a-file)
(insert "blah blah blah")
(save-buffer)
(dired temp-dir))
This should create a temporary directory, a subdirectory "foo" within
that temp dir, it opens a buffer for a file "zzzz" within that
subdirectory "foo", and then a dired buffer on the temp dir. For
example, you'll now have a buffer on file
"/tmp/dired_bug-123abc/foo/zzzz" and a dired buffer on directory
"/tmp/dired_bug-123abc".
3. In the dired buffer, rename the directory "foo" to "bar"
4. Go back to the buffer on "bar" and look at its path (i.e. eval
buffer-file-name, or C-x C-w and look at the path, or just try to
modify the file and then save it)
Expected result: The buffer that was visiting ".../foo/zzzz" will now
visit ".../bar/zzzz" because ".../foo" was renamed to ".../bar"
Observed result: The buffer visiting ".../foo/zzzz" is still visiting
the old path
I think function `dired-rename-subdir' would actually update the file's
path, but when `dired-rename-file' is called to rename the directory, I
think it never calls `dired-rename-subdir' because of the condition
guarding it (dired-aux.el, end of `dired-rename-file', ca. line 1797):
;; See if it's an inserted subdir, and rename that, too.
(when (file-directory-p file)
(dired-rename-subdir file newname))
`file' here is the *old* file name, as far as I can tell. Because the
rename has already been performed, I think `file-directory-p' will
always return nil here. I suspect changing `file' to `newname' in that
invocation of `file-directory-p' might yield the desired result.
A little work with "git blame" says this condition was added in commit
9e5fd29bede, which says that it "[Fixes a] previous manual mis-merge of
dired-aux". However, it looks like the lines surrounding this change
were not modified in quite a long time. I could be misreading, though!

(I'm going through old bug reports that unfortunately weren't resolved
at the time.)
It looks like this was fixed in a patch series ending with:
commit e71c7a7c600bae3337de95d193dd106e9bfa2b4c
Author: Eli Zaretskii <eliz@gnu.org>
AuthorDate: Mon Apr 11 14:31:04 2022 +0300
Fix default-directory of buffers visiting files in renamed directories
Do you still see this problem in the current Emacs tree?

Yes, I think this is now fixed. Thank you to Eli for fixing it, and to you for following up.

Thanks for checking; I'm closing this bug report, then.
