If the original file that the code was copied from had any
Copyright lines, those must be preserved in the new file.
If the original file had no copyright lines, you're not
required to do any archeology to figure out copyrighth
holders, just leave the new file similarly devoid.

Simply moving code is also not a copyrightable enhancement,
so adding your own copyright on moved code is inappropriate.

Once you add new functionality to the newfile though, you
are free to add your own copyright statement at that point,
if desired.
