"Each command in a pipeline is executed as a separate process (i.e., in
a subshell). See COMMAND EXECUTION ENVIRONMENT for a description of a
subshell environment. If the lastpipe option is enabled using the
shopt builtin (see the description of shopt below), the last element of
a pipeline may be run by the shell process."
or maybe
"Builtin commands that are invoked as part of a pipeline are also
executed in a subshell environment."
