Yes, so it will be impossible to unify without changing the
resulting text.  But unless one description is clearly better for
one subcommand while the other description is also clearly better
for the other subcommand, we should be able to pick a better one
that would serve both subcommands, and that way we would improve
description for one subcommand while keeping the other one the same,
right?

Sure, it won't be just "write what is shared across all the transfer
commands in a single file and include it from all".  The direction
of transfer is a reason why the options may differ, of course, so we
may need to have two (or three) include files if we want to go that
route.
