Subject: [PATCH RFC 0/5] Patches to avoid reporting conversion changes.

This is the first go at having the git index keep track of the
conversion mode and corresponding normalized blob for files.

The approach is relatively straight-forward:
  * struct cache_entry has been extended with two fields,
    norm_flags and norm_sha1, to keep track of the data.
  * An accessor function ce_norm_sha1() has been added,
    which checks that the fields seem valid, and otherwise
    recalculates them.
  * run_diff_files() and ce_compare_data() compare against
    the normalized blob.

Still missing is a testsuite, and I may have missed some place
that ought to use ce_norm_sha1().

Thanks to Junio C Hamano for the suggestion.

Henrik Grubbström (Grubba) (5):
  sha1_file: Added index_blob().
  cache: Added ce_norm_sha1() and related cache_entry fields.
  cache: Added index extension "NORM".
  reachable: Made the gc aware of the ce_norm_sha1.
  cache: Use ce_norm_sha1().
