lsp -l cannot take an argument

Perhaps it's a feature, but I expected to be able to do a `lsp -l /path/to/destination/`. However,

``` sh
$ mkdir -p /tmp/a/b
$ ls /tmp/a/
b
$ lsp -l /tmp/a/
Unable to list directory: open /home/kseistrup/ /tmp/a: no such file or directory
$ lsp -l/tmp/a/
[··· 193 lines deleted ···]
                                lsp "~", 181 files, 69 directories
$ 
```

WTF?
