Re: New start up splash screen annoyance...

    . When used in the echo area, it should minimize the number of newlines,
    adding them only when they really add clarity. No assumptions should be made
    about the width or height of a user's echo area. In particular, no filling -
    let the window resize itself or wrap the text if it is too long.

    . When used as a tooltip, it should use newlines as appropriate to make the
    text as clear as possible.

This suggests that we put in newlines for the tooltip case,
and repace them with spaces for display in the echo area.
