+--allow-unsafe-features::
+       Many command-line options can be provided as part of the
+       fast-import stream itself by using the `feature` or `option`
+       commands. However, some of these options are unsafe (e.g.,
+       allowing fast-import to access the filesystem outside of the
+       repository). These options are disabled by default, but can be
+       allowed by providing this option on the command line.  This
+       currently impacts only the `export-marks`, `import-marks`, and
+       `import-marks-if-exists` feature commands.
++
+       Only enable this option if you trust the program generating the
+       fast-import stream! This option is enabled automatically for
+       remote-helpers that use the `import` capability, as they are
+       already trusted to run their own code.
