Excess space in path autocomplete

Every path autocomplete adds space at the end of path.
For example our file is located at `/folder/blabla/dict.txt`

```
$ dict load /folder/bla<tab>
```
Will complete path to 
```
dict load /folder/blabla/(space) _
```
and move cursor after the space, so to type next we should press `<backspace>` and type next name in path every time after using autocomplete.
