Please reply to these messages, keeping 35497@debbugs.gnu.org in To: or Cc:.

Usually, we appreciate a new patch relative to upstream. But in this
case, not changing etc/NEWS, I believe it isn't necessary to send a new
patch until there are other changes you want to show.

Pls do.

Btw, your new test in files-tests.el uses file notifications. Possible
of course. But wouldn't it be more robust to check the inode number of
the involved files, and how it changes, or not? See file-attributes how
to retrieve the inode number of a file.
