Subject: vim-patch:8.1.1015: quickfix buffer shows up in list, can't get
 buffer number

Problem:    Quickfix buffer shows up in list, can't get buffer number.
Solution:   Make the quickfix buffer unlisted when the quickfix window is
            closed.  get the quickfix buffer number with getqflist().
            (Yegappan Lakshmanan, closes vim/vim#4113)
