0.9.0

Version 0.9 adds a new package for interacting with remote Git repositories and expands the packfile package to handle random access.

Added

• A new packfile/client package enables downloading commits from and uploading commits to remote Git repositories. (#7)
• The packfile.DeltaReader type is a flexible way of expanding a deltified object from a packfile.
• The packfile.Undeltifier type decompresses objects from packfiles.
• The packfile.Index type stores a packfile object ID lookup table that is nteroperable with Git packfile index files. (#12)
• packfile.ReadHeader enables random access to a packfile.
• *object.Commit and *object.Tag now implement BinaryMarshaler and BinaryUnmarshaler in addition to TextMarshaler and TextUnmarshaler. This is for symmetry with object.Tree.
• object.Prefix allows marshaling and unmarshaling the "blob 42\x00" prefix used as part of the Git object hash.
• The new *Git.Clone and *Git.CloneBare methods clone repositories.
• git.URLFromPath converts a filesystem path into a URL.

Changed

• The githash package is now the home for the Ref type. This permits ref string manipulation without depending on the larger git package. git.Ref is now a type alias for githash.Ref.

Removed

• Removed the packfile.ApplyDelta function. The packfile.DeltaReader type performs the same function but permits more control over how it's used.

Fixed

• Ref.IsValid produces less false positives than before. (#16)
