Completion for ":cd" from 'cdpath' #374
Description
The `cd` command should consider the `cdpath` setting for completion of
relative paths.
Currently the completion appears to use only the current working directory when
completing relative paths.
This means that `:cd foo<Tab>` should complete `foobar` if there exists
`/path/in/cdpath/foobar` (and `/path/in/cdpath` is in `cdpath`).
