bug#32173: 26.1; wdired: broken 'wdired-use-interactive-rename'

[Enrico Scholz]

Hi,

wdired seems to misbehave when 'wdired-use-interactive-rename' is
active:

1. create scratch directory with a file

   mkdir /tmp/test
   cd /tmp/test
   touch foo.c

2. start emacs

   LC_ALL=C emacs -Q -nw

3. set option above

   M-: (setq wdired-use-interactive-rename t)

4. go into the folder

   C-x C-f /tmp/test

   emacs will show

   | /tmp/test:
   | total used in directory 0 available 4023272
   | drwxrwxr-x.  2 ensc ensc  60 Jul 16 15:16 .
   | drwxrwxrwt. 18 root root 600 Jul 16 15:17 ..
   | -rw-rw-r--.  1 ensc ensc   0 Jul 16 14:58 foo.c

5. enter wdired mode

   C-x C-q

6. replace 'foo' with 'test'; e.g.

   test M-d

7. commit it

   C-c C-c


---> emacs asks

| Move `c' to `test.c'? [Type yn!q or C-h]

or

| Move `.' to `test.c'? [Type yn!q or C-h]

(seems to differ slightly when repeating step 6).  Buffer content is
malformed too (first two lines are merged, or whitespace between time
and filename is removed).


Confirming with 'y' will make the operation fail because the requested
source file does not exist.


Without the interactive rename, things seem to be fine.
