We have to parse out curl's http/2 trace lines so we can redact their headers. We already match two different types of lines from various vintages of curl. In preparation for adding another (which will be slightly more complex), let's pull the matching into its own function, rather than doing it in the middle of a conditional.
While we're doing so, let's expand the comment a bit to describe the two matches. That probably should have been part of db30130165 (http: handle both "h2" and "h2h3" in curl info lines, 2023-06-17), but will become even more important as we add new types.
