commit b4ec771ee4130f283690fec9863fe871f42e395d
Author: Jan Pokorný <jpokorny@redhat.com>

    Fix: -Wformat-truncation=2: prevent format truncation
    
    Discovered thanks to -Wformat-truncation=2 of GCC7.
    
    Actually, some instances could gain more conservative upper bound on
    output size.
