A fast-forward is a special type of merge where you have
character hexadecimal encoding of the hash of the object (possibly
followed by a white space).

pack::
A set of objects which have been compressed into one file (to save

reachable::
- An object is reachable from a ref/commit/tree/tag, if there is a

Synonym for object name.

+ A shallow repository has an incomplete history some of

+ Symbolic reference: instead of containing the SHA1 id itself, it
