/**********************************************************************
  TODO:

- Do comparison line by line, instead of doing a full comparison of
  the text file.  This will save space as we don't need to keep many
  results in memory.  It will also make it possible to do simple
  'comparison' fixes like accepting the result even if a float differed
  in the last decimals.

- Don't buffer lines from the test that you don't expect to need
  again.

- Change 'read_line' to be faster by using the readline.cc code;
  We can do better than calling feof() for each character!

  Read one "line" from the file

  SYNOPSIS
    read_line
    buf     buffer for the read line
    size    size of the buffer i.e max size to read

  DESCRIPTION
    This function actually reads several lines an adds them to the
    buffer buf. It will continue to read until it finds what it believes
    is a complete query.

    Normally that means it will read lines until it reaches the
    "delimiter" that marks end of query. Default delimiter is ';'
    The function should be smart enough not to detect delimiter's
    found inside strings sorrounded with '"' and '\'' escaped strings.

    If the first line in a query starts with '#' or '-' this line is treated
    as a comment. A comment is always terminated when end of line '\n' is
    reached.

  Create a query from a set of lines

  SYNOPSIS
    read_query()
    q_ptr pointer where to return the new query

  DESCRIPTION
    Converts lines returned by read_line into a query, this involves
    parsing the first word in the read line to find the query type.


    A -- comment may contain a valid query as the first word after the
    comment start. Thus it's always checked to see if that is the case.
    The advantage with this approach is to be able to execute commands
    terminated by new line '\n' regardless how many "delimiter" it contain.

    If query starts with @<file_name> this will specify a file to ....
