Patch 7.0.146
Problem:    When 'switchbuf' is set to "usetab" and the current tab has only a
            quickfix window, jumping to an error always opens a new window.
            Also, when the buffer is open in another tab page it's not found.
Solution:   Check for the "split" value of 'switchbuf' properly.  Search in
            other tab pages for the desired buffer. (Yegappan Lakshmanan)
