Clear status line after hop when `cmdheight > 1`

[shyun3]

Re-raising this issue from the original repo: hadronized#276

When I use :HopChar1, the statusline changes to Hop 1 Char: . However, this does not go away after hopping when using more than 1 line for the statusline (when the cmdheight option is greater than 1).

Would it be possible to clear the prompt after hopping no matter how large the statusline is?
