setdiscovery: improves logged message The 'srvheads' list contains all server heads including the common ones. We adjust 'ui.log' message to provide more useful information about server heads locally unknown. The performance impact of turning the list to set is negligible (about 1e-4s) compared to the rest of the discovery cost, so I'm taking the easy path.

tests: handle variation between pure and normal output in annotate --skip I'm pretty sure that both results are valid, depending on how you slice the edits.
