Re: Unix/DOS text mode?

[Joshua <joshuaelson at yahoo dot com>]

Corinna et al,

Strangely enough, my vim does *not* start up with the
fileformats=dos,unix option either.  However, adding
that switch to .vimrc does the trick.  I wonder where
your installation is getting that option set at?

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.
