The --import-marks= option may be specified multiple times on the
commandline and should result in all marks being read in. Only one
import-marks feature may be specified in the stream, which is
overriden by any --import-marks= commandline options.
If one wishes to specify import-marks files in addition to the one
specified in the stream, it is easy to repeat the stream option as a
--import-marks= commandline option.
Also verify this behavior with tests.

New in this series. Without this it is no longer possible to specify
multiple --import-marks= options on the commandline.
