        $ mkdir a
        $ touch a/a\ a.txt a/a\ a.odt
        $ vi a/a<TAB>           [correctly completes to]
        $ vi a/a\ a.<TAB>
a a.ods  a a.txt
        ^C
        $ vi ~/a/a<TAB>         [correctly completes to]
        $ vi ~/a/a\ a.<TAB>     [further tabs do nothing]
        $ vi ~/a/a\ a.t<TAB>    [still nothing]
