Adding the test for the failed parse_ref() is possible, I think. But
since that function is destined to die, as I promised to use

going to have another hard look at refs subsystem for the
gc-not-looking-at-worktree-refs problem, may I make another promise to
add tests after this function is gone?

Never mind. I went ahead and made a test case anyway because why not.

But that's not worth an email. An interesting thing maybe worth
sharing is, if HEAD is broken (the only reason we would fail to create
"struct worktree" for main worktree), then "git worktree list" from
main worktree would fail too, because repo setup code fails to parse
HEAD as well and die(). That makes the "always show main worktree"
patch useless, since we won't get far enough to execute
get_worktrees() in the first place. However, you can still do "git
worktree list" from a linked worktree, gitdir setup code will not stop
you (how can it). And the patch is still needed.
