Ckeditor5: Is the \n character in PO files used correctly?

[Reinmar]

A typical PO files looks like this:

# Copyright (c) 2003-2018, CKSource - Frederico Knabben. All rights reserved.
msgid ""
msgstr ""
"Language: fi\n"
"Language-Team: Finnish (https://www.transifex.com/ckeditor/teams/11143/fi/)\n"
"Plural-Forms: nplurals=2; plural=(n != 1);\n"

msgctxt "Toolbar button tooltip for the Undo feature."
msgid "Undo"
msgstr "Peru"

msgctxt "Toolbar button tooltip for the Redo feature."
msgid "Redo"
msgstr "Tee uudelleen"

What are those \n in Language, Language-Team and Plural-Forms? Also, what is that empty msgid at the beginning (I feel that I asked about this already)?

Looks like standard output from xgettext produces something like this and all examples on the web have those \n.

"An empty untranslated-string is reserved to contain the header entry with the meta information (see Header Entry). This header entry should be the first entry of the file. The empty untranslated-string is reserved for this purpose and must not be used anywhere else." - https://www.gnu.org/software/gettext/manual/html_node/PO-Files.html

What are those n in Language, Language-Team and Plural-Forms

Those \n must end every header, AFAIR to split them. See https://docs.transifex.com/formats/gettext#sample-data
