Subject: bug#57293: 29.0.50; query-replace with Wdired skips symlink target
Date: Thu, 18 Aug 2022 20:11:36 -0700

From "emacs -Q":

1. Create a file foo, and create a symlink bar that points to foo.

S lrwxrwxrwx  1 kupfer kupfer    3 Aug 18 19:48 bar -> foo
  -rw-r--r--  1 kupfer kupfer    0 Aug 18 19:46 foo

2. Visit the directory with dired and type C-x C-q.

3. Move point to the start of the buffer.

4. M-% foo RET baz RET

I expect query-replace to ask me about both the file foo and the symlink
target foo.  That's what Emacs 28.1 does, and it's quite handy.
Instead, query-replace asks me only about the file foo, ignoring the
symlink target.

S lrwxrwxrwx  1 kupfer kupfer    3 Aug 18 19:48 bar -> foo
  -rw-r--r--  1 kupfer kupfer    0 Aug 18 19:46 baz

I can still manually fix the symlink (replace "foo" with "baz") while in
Wdired, but I think query-replace should be able to do this for me.

The build is Emacs master 7dab52dfbc plus a couple local fixes to MH-E,
so I expect it's reproducible with just 7dab52dfbc.
