I've ran into a regression, and reverting this patch fixes it.

Using current master, and the following setup:

    % cd "$(mktemp -d)"
    % mkdir foo

The following two work:

    % make -C <TAB>
    [offers foo]

    % make -C ./fo<TAB>
    [expands to ./foo]

But the following does not:

    % make -C fo<TAB>
    [no matches]

It does work if I revert this patch.
