1. Summarise the issue (what were doing, what went wrong?)

I tried to delete a file from my repo, and rename another to the same
name as the deleted file. Darcs complained that the target of the rename
already exists in the repo, even though it doesn't in the working dir.

2. What behaviour were you expecting instead?

Darcs should allow me to rename the file! I should also be able to use
revert to get back to exactly where I was (both files existing and with
the correct contents)

Assuming file foo contains one line: "foostuff" and other contains one
line: "otherstuff", I would like to see something like this in whatsnew,
after executing `rm foo && darcs mv other foo`:

    hunk ./foo 1
    -foostuff
    rmfile ./foo
    move ./other ./foo

Note that the move cannot be commuted past the rmfile!

3. What darcs version are you using? (Try: darcs --exact-version)

2.9.8 (+ 18 patches)

4. What operating system are you running?
  
Ubuntu 13.10 X86_64

I've just sent a failing testcase for this

Interestingly, it is possible to do:

rm foo
darcs rec -am 'Remove foo'
darcs move other foo
darcs amend # Add the move to the last patch

to get to a patch with the desired changes, so this is just a UI issue.

Sounds like a pending patch issue.
