Oops! I'm not actually familiar with the Thunderbird source's organization, so I just went by what was marked as owned by Thunderbird in that wiki page I linked

  In practice, Thunderbird is all of comm-central sans suite/ and chat/. calendar/ used to be Sunbird [a standalone calendar client], but those people decided to channel all of their resources into Lightning instead, so all of the Sunbird-specific stuff was ripped out. Lightning is strictly speaking an independent project from Thunderbird, but it is far and away the most-used extension in Thunderbird and parts of it (particularly the backend) have essentially moved into the TB distribution for various policy reasons. There's some other stuff that's basically build system, release engineering, or testing gunk, but that stuff is mostly Python anyways and won't impact the SLOC metrics too badly.
