can properly trickle down from cmd_*.

Alexander Neumann 83eb075e3a Resolve name collisions
At the moment when two items to be saved have the same directory name,
restic only saves the first one to the repo. Let's say we have a
structure like this:

    dir1
    └── subdir
        └── file
    dir2
    └── subdir
        └── file

When restic is run on `dir1/subdir` and `dir2/subdir`, it will only save
the first `subdir`:

    $ restic backup dir1/subdir dir2/subdir
    [...]

    $ restic ls -l latest
    drwxr-xr-x  1000   100      0 2017-08-27 20:56:39 /subdir
    -rw-r--r--  1000   100     17 2017-08-27 20:56:39 /subdir/file

That's obviously a bad thing, caused by an early decision to strip the
full path to the files/dirs to save and only leave the last directory.

This commit partly resolves this by handling colliding names and
resolving the conflicts. Restic will now append a counter to the file
(`-123`) until the conflict is resolved. So in the example above, we'll
end up with the following structure:

    $ restic ls -l latest
    drwxr-xr-x  1000   100      0 2017-08-27 20:56:39 /subdir
    -rw-r--r--  1000   100     17 2017-08-27 20:56:39 /subdir/file
    drwxr-xr-x  1000   100      0 2017-08-27 20:56:46 /subdir-1
    -rw-r--r--  1000   100     17 2017-08-27 20:56:46 /subdir-1/file

This partly addresses #549 and closes #1179.

At first I thought that the obvious correction would be to archive the
full path. But it turns out that collisions may still occur: Suppose you
have a file named `foo` in the current directory, and the parent directory
also contains a file `foo`. Archiving these with restic also causes a
collision, since restic strips the `../` from the first file:

    $ restic backup ../foo foo

This also happens with `tar`, which does not handle the collision and
will happily archive two files called `foo`.

So, the best way forward is to handle name collisions and archive the
whole path. The latter will be tackled in a separate PR.

Emil Hessman c2ff7150aa internal: check error before deferring file Close()
If there is an error, file will be `nil`. We should check the returned error before deferring file `Close()`.
