It's described in the COMMAND EXECUTION section. The execution environment
for shell builtins and functions is the same as the shell environment: it
has none of the changes described in the "simple command other than a
builtin or shell function" execution environment. In particular, the signal
handlers and trapped signals are identical to the calling shell.
