51 cmd=branches gives 4 nodeids (head, root, first parent, second parent) per line (few lines possible, per branch, perhaps?)
52 cmd=capabilities gives lookup ...subset and 3 compress methods
53 // lookup changegroupsubset unbundle=HG10GZ,HG10BZ,HG10UN
54 cmd=heads gives space-separated list of nodeids (or just one)
55 nodeids are in hex (printable) format, need to convert fromAscii()
56 cmd=branchmap
57 cmd=between needs argument pairs, with first element in the pair to be head(!), second to be root of the branch (
58 i.e. (newer-older), not (older-newer) as one might expect. Returned list of nodes comes in reversed order (from newer
59 to older) as well
