There is not really a second line.
Let's say, <EoF> is the end of file indicator, <LF> the line feed, and let's forget about end of page indicators.

When you open an empty file with your editor (you call it "open manually"), it sees <EoF>, and thus shows
1|

When you create a file without contents with Ada.Text_IO and close it again, your editor sees <LF><EoF>, and thus shows
1|
2

The reason is the <LF> written by Ada according to RM.
