I meant if the original cwd lies within the repository.

Example:

 repo		/tmp/git/.git
 starting cwd	/tmp/git/.git/objects/pack

git.txt is confusing, then.  Actually it has some other insights:

 --work-tree=<path>
	Set the path to the working tree. The value
	will not be used in combination with
	repositories found automatically in a .git
	directory (i.e. $GIT_DIR is not set).

So GIT_WORK_TREE should be discarded or warned about when GIT_DIR is
not set. (?)

	This can also be controlled by setting the
	GIT_WORK_TREE environment variable and the
	core.worktree configuration variable. It can be
	an absolute path or relative path to the
	directory specified by --git-dir or GIT_DIR.

This is where I got the impression about relative paths.

	Note: If --git-dir or GIT_DIR are specified but
	none of --work-tree, GIT_WORK_TREE and
	core.worktree is specified, the current working
	directory is regarded as the top directory of
	your working tree.

Nice to see this case is documented.

Speaking of which, it is not clear to me that core.worktree should
fall under the forbidden case discussed above.  If it does, what is
the point of making it configurable?

Thanks for checking.
