+" The current parser is a bit lax about parsing. For example, given this:
+" snippet foo"bar"
+" it treats `foo"bar"` as the trigger. But with this:
+" snippet foo"bar baz"
+" it treats `foo` as the trigger and "bar baz" as the description.
+" I think this is an accident. Instead, we'll assume the description must
+" be surrounded by spaces. That means we'll treat
+" snippet foo"bar"
+" as a trigger `foo"bar"` and
+" snippet foo"bar baz"
+" as an attempted multiword snippet `foo"bar baz"` that is invalid.
+" NB: UltiSnips parses right-to-left, which Vim doesn't support, so that makes
+" the following patterns very complicated.

+" We want to match a trailing " as the start of a doc comment, but we also

+" So we have to define this twice, once in the general case that matches a
+" trailing " as the doc comment, and once for the case of the multiword
+" delimiter using " that has more constraints
