Subject: vim-patch:7.4.2049

Problem:    There is no way to get a list of the error lists.
Solution:   Add ":chistory" and ":lhistory".

Problem:    When using ":vimgrep" may end up with duplicate buffers.
Solution:   When adding an error list entry pass the buffer number if possible.

Problem:    Line numbers in the error list are not always adjusted.
Solution:   Set b_has_qf_entry properly. (Yegappan Lakshmanan)
