This flag tells the command not to reuse existing deltas

but compute them from scratch.
|

|
||||
--delta-base-offset::
|
||||
A packed archive can express base object of a delta as
|
||||
either 20-byte object name or as an offset in the
|
||||
stream, but older version of git does not understand the
|
||||
latter. By default, git-pack-objects only uses the
|
||||
former format for better compatibility. This option
|
||||
allows the command to use the latter format for
|
||||
compactness. Depending on the average delta chain
|
||||
length, this option typically shrinks the resulting
|
||||
packfile by 3-5 per-cent.
