Merge branch 'cc/replace-object-info'

read_sha1_file() that is the workhorse to read the contents given
an object name honoured object replacements, but there is no
corresponding mechanism to sha1_object_info() that is used to
obtain the metainfo (e.g. type & size) about the object, leading
callers to weird inconsistencies.

* cc/replace-object-info:
  replace info: rename 'full' to 'long' and clarify in-code symbols
  Documentation/git-replace: describe --format option
  builtin/replace: unset read_replace_refs
  t6050: add tests for listing with --format
  builtin/replace: teach listing using short, medium or full formats
  sha1_file: perform object replacement in sha1_object_info_extended()
  t6050: show that git cat-file --batch fails with replace objects
  sha1_object_info_extended(): add an "unsigned flags" parameter
  sha1_file.c: add lookup_replace_object_extended() to pass flags
  replace_object: don't check read_replace_refs twice
  rename READ_SHA1_FILE_REPLACE flag to LOOKUP_REPLACE_OBJECT
