    buildhistory-diff: reduce PKGR noise
    
    When using PR service the buildhistory-diff output contains a lot of
    PKGR changes: In practice the mass of PKGR updates hide other important
    changes as they often account for 80% of all changes.
    
    Skipped incremental and decremental changes of PKGR versions to reduce
    amount of the script output. All changes are still included in the
    output if script is run with -a/--report-all command line option.
