Auto complete of directories with spaces in their name does not work correctly.

[J0hn-Lawrence]

Describe the bug
Auto complete of directories with spaces in their name does not work correctly.

To Reproduce
Steps to reproduce the behavior:

1. Open Wave
2. Create a directory called something like 'Test dir'
3. type ls and a space and then hit Tab to auto complete
4. Select the newly created directory by hitting enter
5. Enter the command by hitting Enter again
6. See error

Expected behavior
I would expect the auto completion to add single quotes around the directory name such that the shell can then find the auto completed directory and it works.
