Re: [PATCH] t0027: Add repoMIX and LF_nul

> "new safer autocrlf handling":
>   Check if eols in a file are converted at commit, when the file has
>   CR (or CLLF) in the repo (technically speaking in the index).
>   Add a test-file repoMIX with mixed line-endings.
>   When converting LF->CRLF or CRLF->LF: check the warnings

> checkout_files():
>   Checking out CRLF_nul and checking for eol coversion does not
>   make much sense (CRLF will stay CRLF).
>   Use the file LF_nul instead: It is handled a binary in "auto" modes,
>   and when declared as text the LF may be replaced with CRLF, depending
>   on the configuration
