    Correct and optimize the computation of logical column position (the
    one that takes account of tabs).

    Add --version to eg/predump, and document all options with double
    dashes.

    Silence 'uninitialized' warning generated by /(?<=.{35})/.
    Thanks to Brian Fraser for reporting this.

    Try to quell weird Win32 test failures which seem to occur only in
    tests where I am using 'use open' to put the standard handles into
    UTF-8 mode. The fix (I hope) is to do this to the Test::Harness
    handles at run time instead of to the standard handles at compile
    time.

    Add file CONTRIBUTING.
