It took me a while to find that dired-async-mode is implemented
in the package emacs-async. Then tried to rename with Wdired,
and it works. Then tried to rename with R, and it fails with:
Debugger entered--Lisp error: (wrong-type-argument stringp nil)
make-process(:name "emacs" :buffer #<buffer *emacs*> :stderr #<buffer
*emacs:err*> ...
async-start-process("emacs" ...
apply(async-start-process "emacs" ...
async-start((lambda nil (require 'cl-lib) (require 'dired-aux) ...
dired-async-create-files(dired-rename-file "Move" ...
dired-async--smart-create-files(...
dired-create-files(dired-rename-file "Move" ...
dired-do-create-files(move dired-rename-file "Move" nil t "Rename")
dired-do-rename(nil)
funcall-interactively(dired-do-rename nil)
command-execute(dired-do-rename)
Then noticed that this backtrace doesn't include the function
that uses dired-vc-rename-file. So I disabled dired-vc-rename-file,
and got the same error.
This means that the bug is not in Emacs and should be reported to the
maintainers of the emacs-async package.
