[PATCH v2 1/1] Document how to normalize the line endings

[tboegi@web.de]

From: Torsten Bögershausen <tboegi@web.de>

The instructions how to normalize the line endings should have been updated
as part of commit 6523728499e 'convert: unify the "auto" handling of CRLF',
(but that part never made it into the commit).

Update the documentation in Documentation/gitattributes.txt
and add a test case in t0025.
