      [My previous solution for handling multiple blank lines at the
      beginning only handled up to two blank lines at the beginning]

      I think the following is the solution:

      substitute(@a, '^\(\s*\n\)*\|\n\s*\n\@=', '', 'g')

      I have tested it with 0 or more blank lines at the beginning,
      at the end and in between two non-trivial lines; blank lines
      with and without white space; non-trivial lines starting and
      ending with and without blank space.
