Define a constant for 127 in DeltaEncoder
The special value 127 here means how many bytes we can put into a single insert command. Rather than use the magical value 127, lets name it to better document the code. Change-Id: I5a326f4380f6ac87987fa833e9477700e984a88e Signed-off-by: Shawn O. Pearce <spearce@spearce.org>
