When "git fsck" reports a broken link (e.g. a tree object contains
a blob that does not exist), both containing object and the object
that is referred to were reported with their 40-hex object names.
The command learned the "--name-objects" option to show the path to
the containing object from existing refs (e.g. "HEAD~24^2:file.txt").

* js/fsck-name-object:
fsck: optionally show more helpful info for broken links
fsck: give the error function a chance to see the fsck_options
fsck_walk(): optionally name objects on the go
fsck: refactor how to describe objects

+

+OUTPUT
+------
+
+The output of "git fetch" depends on the transport method used; this
+section describes the output when fetching over the Git protocol
+(either locally or via ssh) and Smart HTTP protocol.
+
+The status of the fetch is output in tabular form, with each line
+representing the status of a single ref. Each line is of the form:
+
+-------------------------------
+ <flag> <summary> <from> -> <to> [<reason>]
+-------------------------------
+
+The status of up-to-date refs is shown only if the --verbose option is
+used.
+
+In compact output mode, specified with configuration variable
+fetch.output, if either entire `<from>` or `<to>` is found in the
+other string, it will be substituted with `*` in the other string. For
+example, `master -> origin/master` becomes `master -> origin/*`.
+
+flag::
+       A single character indicating the status of the ref:
+(space);; for a successfully fetched fast-forward;
+`+`;; for a successful forced update;
+`-`;; for a successfully pruned ref;
+`t`;; for a successful tag update;
+`*`;; for a successfully fetched new ref;
+`!`;; for a ref that was rejected or failed to update; and
+`=`;; for a ref that was up to date and did not need fetching.
+
+summary::
+       For a successfully fetched ref, the summary shows the old and new
+       values of the ref in a form suitable for using as an argument to
+       `git log` (this is `<old>..<new>` in most cases, and
+       `<old>...<new>` for forced non-fast-forward updates).
+
+from::
+       The name of the remote ref being fetched from, minus its
+       `refs/<type>/` prefix. In the case of deletion, the name of
+       the remote ref is "(none)".
+
+to::
+       The name of the local ref being updated, minus its
+       `refs/<type>/` prefix.
+
+reason::
+       A human-readable explanation. In the case of successfully fetched
+       refs, no explanation is needed. For a failed ref, the reason for
+       failure is described.
