qcd: Enable `cd` into paths with spaces

Previously, the `awk` command would only print out the second column,
meaning that if we had a database entry like:

    qproj	/Users/user/code/Q Proj

`awk` would give us:

    /Users/user/code/Q

(missing the " Proj" part).

Output all columns except the first using this `awk` substitution by Ed
