[PATCH v2] blame: CRLF in the working tree and LF in the repo

["Torsten Bögershausen" <tboegi@web.de>]

A typicall setup under Windows:
core.eol is CRLF and a file is marked as "text" in .gitattributes,
or core.autocrlf is true

After 4d4813a5 "git blame" no longer works as expected,
every line is annotated as "Not Committed Yet",
even though the working directory is clean.

commit 4d4813a5 removed the conversion in blame.c for all files,
with or without CRLF in the repo.

Having files with CRLF in the repo and core.autocrlf=input is a temporary
situation, the files should be normalized in the repo.
Blaming them with "Not Committed Yet" is OK.

The solution is to revert commit 4d4813a5.

What happened to the test cases ?
They where improved, but it turned out that they failed
from time to time, both Windows and Mac OS.
"Spicing them" with test_tick or other things didn't help,
if they are run in a tight loop.
running with "debug=t verbose=t ./t8003*.sh" make the test
pass.
My suggestion is to revert 4d4813a5 and drop TC's for the moment.
