Re: [PATCH/RFC v3 14/16] transport-helper: add import|export-marks to fast-import command line.

fast-import internally uses marks that refer to an object via its sha1.
Those marks are created during import to find previously created objects.
At exit the accumulated marks can be exported to a file and reloaded at
startup, so that the previous marks are available.
Add command line options to the fast-import command line to enable this.
The mark files are stored in info/fast-import/marks/<remote-name>.
