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