    Defines: strrpt()

    strrpt(dst, src, k) "RePeaTs" the string src into dst k times.  E.g.
    strrpt(dst, "hack ", 2) will move "hack hack" to dst.  If k <= 0 it
    does nothing.  The result is the number of characters moved, except
    for the closing NUL.  src may be "" but may not of course be NullS.
