Merge branch 'sr/gfi-options'
* sr/gfi-options: fast-import: add (non-)relative-marks feature fast-import: allow for multiple --import-marks= arguments fast-import: test the new option command fast-import: add option command fast-import: add feature command fast-import: put marks reading in its own function fast-import: put option parsing code in separate functions
