Values spanning multiple lines (e.g. a multi-line FORGIT_*_GIT_OPTS export) were silently dropped: read stopped at the first newline and IFS only split on spaces, so the resulting array came out empty. Split on spaces, tabs and newlines and consume the whole value with an empty delimiter, ignoring leading/trailing whitespace. Add unit tests covering space-, tab- and newline-separated inputs.
