Here I may want to keep the content similar to the original paragraph.
But if you say so, it will be fine.

Maybe I am a little confused: this two "-" meaning? Shouldn't it be the
same paragraph?

-       This option can be used to specify a shell command that will
-       be called to automatically add or modify a trailer with the
-       specified <token>.
+       This option can be used to specify a shell command that will be called:
+       - once to automatically add a trailer with the specified
<token>, and then
+       - each time a '--trailer <token>=<value>' argument to modify
the <value> of
+       the trailer that this option would produce.

Wouldn't it be weird?

Thanks a lot!
It looks more professional than what I wrote.
