[darcs-users] Behaviour of add, with non-existent filenames

[Iago Abal]

Are you using the last version of Darcs?

$ darcs --version
2.5.2 (release)
$ mkdir repo
$ cd repo/
repo$ darcs init
repo$ mkdir subdir
repo$ cd subdir
repo/subdir$ darcs add foo
darcs: subdir/foo: getSymbolicLinkStatus: does not exist (No such file or
directory)
repo/subdir$ echo $?
1
repo/subdir$ darcs wh
No changes!
