From: Johan Herland <johan@xxxxxxxxxxx>
The 'marks' capability is reported by the remote helper if it requires
the fast-import marks database to loaded/saved by any git-fast-import
process that is provided by the transport machinery. The feature is
advertised along with exactly one argument: the location of the file
containing the marks database.

'import'::
This helper supports the 'import' command.
+'marks' filename::
+ Helper requires the marks from a git-fast-import run to be
+ loaded from, and saved to, the given filename. When this
+ "feature" is advertised, each git-fast-import run must load
+ and save the internal marks database (see the --import-marks
