character hexadecimal encoding of the hash of the object (possibly
followed by a white space).

One of the identifiers "commit","tree","tag" and "blob" describing
the type of an object.

pack::
A set of objects which have been compressed into one file (to save
local head, the push fails.
reachable::
- An object is reachable from a ref/commit/tree/tag, if there is a
- chain leading from the latter to the former.
+ All of the ancestors of a given commit are said to be reachable from

To clean a branch by starting from the head of the main line of

it as my origin branch head".

repository::
SHA1::
Synonym for object name.
+shallow repository::
+ A shallow repository has an incomplete history some of

+ words, git is told to pretend that these commits do not
+ have the parents, even though they are recorded in the
+ commit object). This is sometimes useful when you are
+ interested only in the recent history of a project even
+ though the real history recorded in the upstream is
+ much larger. A shallow repository is created by giving
+ `--depth` option to gitlink:git-clone[1], and its
+ history can be later deepened with gitlink:git-fetch[1].
+
+symref::
+ Symbolic reference: instead of containing the SHA1 id itself, it
+ is of the format 'ref: refs/some/thing' and when referenced, it
+ recursively dereferences to this reference. 'HEAD' is a prime
+ example of a symref. Symbolic references are manipulated with
+ the gitlink:git-symbolic-ref[1] command.
