Use alternate screen only when the value of height is 100%

Browse Source 
Do not automatically decide to use alternate screen when the value of
height exceeds the height of the terminal.

    # Use alternate screen
    fzf
    fzf --height 100%
    fzf --no-height

    # Still use current screen
    fzf --height 10000
