Title: Explain match behaviour for variable length relationship->node hops in more detail

Hey @nawroth, I missed this explanation when reading the docs so I tested how it works to document it, just to have `rebase` tell me you added it recently. However, I'm not entirely happy with your version ;-)

As you explain it, either the lower or the upper bound may be omitted, however they may both be omitted entirely, including the dots. This change addresses this and also documents the default values used (_infinity_ should also serve nicely as an indicator to think about whether really wants to omit the upper bound).

@systay could you have I quick look if my empirical data matches the engine's implementation? Thanks!
