[Lazarus] Resource strings and newline

[Juha Manninen]

Could somebody please explain what happens when there is #13#10 in a
resource string.

See issue
  http://bugs.freepascal.org/view.php?id=26343
and a note:
  http://bugs.freepascal.org/view.php?id=26343#c75738

It is converted to \n in .po file strings.
However Format() does not convert \n. How can it work?
I will do more experiments later today.

Regards,
Juha
