Description:
        Autocompletion fails for files starting with an opening square bracket 
and having closing bracket somewhere in the filename.

Repeat-By:
        $ mkdir temp && cd temp
        $ mkdir -p one/{\[bad\]\ folder,\[yet\]\ another\ bad\ folder}

        Now try

        $ cd one<TAB>    # cd one/\[   ← should appear

        $ mkdir -p \[one\]/{\[bad\]\ folder,\[yet\]\ another\ bad\ folder}

        Type

        $ cd [<TAB>   # cd \[one\]/   ← should appear
        $ cd \[one\]/<TAB>    ← further completions do not work

        $ mkdir -p \[two\]/{\[bad\]\ folder,\[yet\]\ another\ bad\ folder}

        $ cd [<TAB>  # cd \[   ← should appear
        $ cd \[t<TAB>  # ← doesn’t work.
        $ cd \[tw<TAB>  # ← doesn’t work.
        $ cd \[two<TAB>  # ← doesn’t work.
        $ cd \[two]<TAB>  # ← doesn’t work.
        $ cd \[two\]<TAB>  # ← doesn’t work.

        But if you type

        $ cd [two<TAB>  # cd \[two\]/  ← should appear

        Surprise — this works! However…

        $ cd \[two\]/<TAB>  # ← no further completions work :(
