vim-patch:7.4.1758

Problem:    Triggering CursorHoldI when in CTRL-X mode causes problems.
Solution:   Do not trigger CursorHoldI in CTRL-X mode. Add "!" flag to
            feedkeys() (test with that didn't work though).

vim-patch:7.4.1759

Problem:    When using feedkeys() in a timer the inserted characters are not
            used right away.
Solution:   Break the wait loop when characters have been added to typebuf.
            use this for testing CursorHoldI.

Problem:    feedkeys('i', 'x') gets stuck, waits for a character to be typed.
Solution:   Behave like ":normal". (Yasuhiro Matsumoto)
