You could rename got_worktree_path_info_version() to
got_worktree_fileindex_version() for clarity.

While we're at it we could also print the work tree format version,
stored in .got/format. So I was thinking we would provide a function
which returns two output arguments, the work tree format version and
the file index version.

That said, your patch is fine, too. The easiest way to extend the
approach you took would be another got_worktree_format_version()
function which returns the number stored in .got/format.`
