[Oleh Krehel]

branch: master
commit 74bb138e92042f039d1f418ba7829b92b593591b
Author: Stephen Whipple <address@hidden>
Commit: Oleh Krehel <address@hidden>

    Update ivy format functions.
    
    `ivy-format-function' now accessible via Customize system.
    
    `ivy-format-function-default' and `ivy-format-function-arrow'
    simplified.
    
    New format `ivy-format-function-line' added.
    
    `counsel-M-x' restores `ivy-format-function' before executing command.
    
    Fixes #306
