[elpa] master adac116 126/167: Make ivy-completing-read handle history as cons

branch: master
commit adac116cd79d26585263b90c4559fef8177c4a1c

    Make ivy-completing-read handle history as cons
    
    The ivy-read function assumes that history is a symbol, hence
    ivy-completing-read now makes sure that a symbol is given to
    ivy-read.
    
    Moreover, it makes sure that the value of initial-input is
    coherent with the value of the HISTPOS part of the history
    variable if it exists.
    
    Fixes #295
