  If you have a file commited with CRLF into the index, it will have CRLF in the working tree.
  If the file had been commited with LF into the index, it will have LF in the working tree.
  That is what the documentation tries to say, I think.

However, the above discussion is only valid, when the "text" attribute is defined.
Otherwise the eol attribute has no effect.
So you need something like
* text=auto
and/or
*.txt text
in your .gitattributes file

Do you have a .gitattributes file ? Or not ? Is the file a new one, or does it exist ?

In any way, git ls-files --eol may help to find out, what is in the index and what is in the workingtree.
