[PATCH v2 0/3] CRLF-Handling: bug fix around ce_compare_data()

[tboegi@web.de]

From: Torsten Bögershausen <tboegi@web.de>

Changes since v1:
  - Re-order the patches
  - t6038; use crlf on all platforms
    This did actually not break anything (without old 7/10)
    Adapt the commit message
  - ce_compare_data():
    Simplify the logic around free() in has_cr_in_index(),
    Thanks Eric Sunshine

Break up the old 10/10 series about CLRF handling into smaller
series.

1/10..4/10 are now found in tb/core-eol-fix

This series includes 3 from the 10/10 series:
05/10 read-cache: factor out get_sha1_from_index() helper #now 1/3
10/10 Fix for ce_compare_data(), done right.              #now 2/3
09/10 t6038; use crlf on all platforms                    #now 3/3

The most important patch is 2/3

The reminding 3 patches,
stream-and-early-out,
convert-unify-the-auto-handling-of-CRLF
more-safer-crlf-handling-with-text-attr
Need to be re-done, re-sorted and re-written, thanks for all the comments.

Torsten Bögershausen (3):
  read-cache: factor out get_sha1_from_index() helper
  convert: ce_compare_data() checks for a sha1 of a path
