`rename-file' with leading spaces in filename

[martin rudalics]

With GNU Emacs 22.0.50.1 (i386-mingw-windows98.3000):

Suppose I have a file called "c:/foo"

Doing M-x rename-file RET c:/foo RET c:/ foo
      M-x rename-file RET c:/ foo RET c:/foo

gets me:

File c:/foo already exists; rename to it anyway? (y or n)

After confirmation Emacs renames as expected, the behavior is, however,
inconsistent since the first rename didn't ask for a confirmation.


Suppose now I have two files called "c:/ foo" (one leading space)
and "c:/  foo" (two leading spaces).

Doing M-x rename-file RET c:/ foo RET c:/foo

gets me:

File c:/foo already exists; rename to it anyway? (y or n)

If I now confirm, the file "c:/  foo" (two leading spaces) is deleted and
"c:/ foo" (one leading space) renamed to "c:/foo".  That's unfriendly.
