Re: Format by example

[Dr . Jürgen Sauermann]

    Hi Bill,
      
      I believe I have fixed this, SVN 1334.
      
      However, I would try to avoid "format by example" where possible.
      It looks simple at
      first glance, but seems to allow somewhat  quirky format strings
      (e.g. numbers with
      multiple decimal points) whose proper implementation would require
      far more effort
      than the current implementation.
      
      Best Regards,
      Jürgen
