The watchheader key supports only a single value. Supporting multiple watchheader values was mentioned in discussion [1] of 8d3e3bd8 (doc: explain publicinbox.<name>.watchheader, 2019-10-09), and it wasn't clear if there was a need. One scenario in which matching multiple headers would be convenient is when someone wants to set up public-inbox archives for some small projects but does _not_ want to run mailing lists for them, instead allowing others to follow the project by any of the pull mechanisms. Using a common underlying address, an address alias for each project is configured via a third-party email provider, with messages for each alias being exposed as a separate public-inbox archive. In this setup, messages for an inbox cannot be selected by a List-ID header but can be identified by the inbox's address in either the To or Cc header. To support such a use case, update the watchheader handling to consider multiple values, accepting a message if it matches any value. While selecting a message based on matching _any_ rather than _all_ values is motivated by the above scenario, it's worth noting that the "any" behavior is consistent with how multiple listid config values are handled.
