patch 8.0.1384: not enough quickfix help; confusing winid
Problem: Not enough quickfix help; confusing winid.
Solution: Add more examples in the help. When the quickfix window is not
present, return zero for getqflist() with 'winid'. Add more tests
for jumping to quickfix list entries. (Yegappan Lakshmanan, closes
#2427)

+ *quickfix-title*
+Every quickfix and location list has a title. By default the title is set to

+functions can be used to get the title of a quickfix and a location list
+respectively. The |setqflist()| and |setloclist()| functions can be used to

+ *quickfix-context*
+Any Vim type can be associated as a context with a quickfix or location list.
+The |setqflist()| and the |setloclist()| functions can be used to associate a
+context with a quickfix and a location list respectively. The |getqflist()|
+and the |getloclist()| functions can be used to retrieve the context of a
+quickifx and a location list respectively. This is useful for a Vim plugin
+dealing with multiple quickfix/location lists.
+Examples: >

+ call setqflist([], 'a', {'context' : somectx})
+ echo getqflist({'context' : 1})
+
+ let newctx = ['red', 'green', 'blue']

+ *quickfix-parse*
+You can parse a list of lines using 'erroformat' without creating or modifying
