Did you test it? The command inside $(...) is run in its own sub-process,
therefore, the die() does not exit the caller, just the sub-process, and
the || exit *is* required.

BTW, I think that || exit is sufficient; you don't need to add another
error message - the one that resolve_relative_url() prints is sufficient.
