After I eval:
(let ((default-directory "/tmp"))
(list (read-directory-name "foo" "/tmp/src/")
(read-directory-name "foo" "/tmp/src//")
(read-directory-name "foo" "src/")
(read-directory-name "foo" "src//")
(read-directory-name "foo" "foo//src/")
(read-directory-name "foo" "foo//src//")))
and hit RET RET RET RET, I get :
("/tmp/src/" "/" "src/" "/" "/src/" "/")
Is this intended ?
We could normalize the directory name via expand-file-name in all cases,
e.g. :
modified lisp/files.el
@@ -648,8 +648,7 @@ read-directory-name
(unless dir
(setq dir default-directory))
(read-file-name prompt dir (or default-dirname
- (if initial (expand-file-name initial dir)
- dir))
+ (expand-file-name (or initial "") dir))
mustmatch initial
'file-directory-p))
but the docstring states "Value is not expanded---you must call
`expand-file-name' yourself." so I guess the behaviour is important (and
I guess e.g. for tramp).
Should read-file-name be fixed or should the callers make sure to not
use double slashes ?
