"You" presumably meaning "the person who committed the change" rather than "the user who downloaded the automated 
build", as the user who downloaded the automated build not only might not have a Git repository for Wireshark, they 
might not even have Git.

Perhaps we should have a page on some wireshark.org where a user can enter some identifier for an automated build and 
an SHA hash for a commit and find out whether that build has that commit, and perhaps also say "take me to the latest 
automated build for {pick your target for binary builds} that has this commit" (or fail if there's no such build yet).
