File not found error, if the file path or the file name contains spaces.

Works fine on follow way:
```
sudo compsize -x /path/to/file.extension
# get normal output
```

Does not work if the file path contains spaces.

```
sudo compsize -x /path incl space/to/file.extension
No files. # output
```

Does not work if the file name contains spaces.

```
sudo compsize -x /path/to/file name incl space.extension
No files. # output
```
