265# - parameter $1 : core.eol lf | crlf
266# - parameter $2 : core.autocrlf false | true | input

268# - parameter $4 : reference for a file with only LF in the repo
269# - parameter $5 : reference for a file with only CRLF in the repo
270# - parameter $6 : reference for a file with mixed LF and CRLF in the repo
271# - parameter $7 : reference for a file with LF and CR in the repo (does somebody uses this ?)
