Interesting. I have no such option set explicitely. When opening
vi and then call `:set fileformats', the output is
fileformats=unix,dos
And this is the default setting on Unix systems. Cygwin is treated as
a Unix system by vim.

You're right. It examines the whole file but the notes are clear:
- If _all_ lines end in CRLF, it's treated as dos file.
- If _one_ line is found with only a LF, unix is preferred over dos.
