[elpa] master 0c85d9a 58/67: Add a custom `ivy-count-format'

[Oleh Krehel]

branch: master
commit 0c85d9ac62a67e8cc175a19779cf28876fc58930
Author: Oleh Krehel <address@hidden>
Commit: Oleh Krehel <address@hidden>

    Add a custom `ivy-count-format'
    
    * ivy.el (ivy-count-format): New defcustom.
    (ivy-read): Use `ivy-count-format', unless PROMPT already has a %d spec.
    
    Set `ivy-count-format' to nil or "" if you don't want to see an
    auto-updating match count in the minibuffer.
    
    Re #23.
