Author: John Mastro <address@hidden>

    Fix a small incompatibility in ibuffer
    
    Translate nil values from column functions to the empty string, so that
    subsequent calls to string-width don't signal an error (Bug#26317).
    * lisp/ibuffer.el (ibuffer-compile-format): If a column function returns
    nil, treat it like the empty string.
