NAME u - create a UNIX subshell
SYNOPSIS u
[shell_command]
DESCRIPTION The u macro is a general
escape to a UNIX shell. If invoked with arguments, the arguments
are executed as a command by the Bourne shell, /bin/sh .
Without an argument, an interactive subshell is spawned. The
program used for the subshell is taken from the environment
variable SHELL, if set. Otherwise, the Bourne shell
is used. Exit the subshell to return to spec.
Don't launch spec again from the subshell.
