It's different because it's explicitly designed for convenient execution
of a single command.  Thus, autocommit off would be useless and
counterproductive.  Also, since the -c string is fed to PQexec as a
single query (again different from the psql stdin behavior), if you do
put multiple commands into -c then you get them executed as a single
transaction anyway.  So you do not need or want .psqlrc modifying the
behavior in either case.

One of the reasons for taking autocommit control out of the backend and
pushing it up to the client level is exactly to make it feasible to take
these sorts of application-level considerations into account when
choosing the behavior.
