Hmm. You are not making anything worse here, as we already do not check
the return value of getcwd. But what happens if it fails? Looks like we
currently get a segfault, and the new code will silently set the
variable to the empty string. Neither is particularly helpful.
Should we be using the xgetcwd helper that you add in the next patch?

Ditto here.
