Right, I wasn't expecting it to actually create an archive, that was
just a convenient way to make it fail.

If you prefer, here is another version, which fails due to permissions:

$ mkdir a
$ chmod -xw a
$ mkdir b
$ touch b/c
$ tar cfv a/d.tar --remove-files b
tar: a/d.tar: Cannot open: Permission denied
tar: Error is not recoverable: exiting now
$ ls b
c
$ tar cfvz a/d.tar --remove-files b
tar: a/d.tar: Cannot open: Permission denied
tar: Error is not recoverable: exiting now
b/
b/c
tar: Child returned status 2
tar: Error exit delayed from previous errors
$ ls b
ls: cannot access b: No such file or directory
$ ls
a/


the point is that tar should actually 'exit now' when it says 'exiting
now' instead of proceeding to delete the files without putting them in
a usable archive.
