The current protocol EBNF allows command-request to end with the capability list, if no command specific arguments follow, but the protocol requires that after the capability list, there must be a delim-pkt regardless of the number of command specific arguments. Fixed the EBNF to match. Both JGit and libgit2's implementation has the delim-pkt as mandatory. JGit's code is not publicly linkable, but libgit2 is linked below[1]. As for currently implemented commands on v2 (ls-ref and fetch), the delim packet is already being passed through
