The "auto-GUI" feature (i.e. --ui implied when run without arguments)
only works when the program's stdin is a terminal, which isn't the
case for the GUI's command prompt.
Making it behave like a terminal (i.e. making isatty(0) return true in
the child process) is non-trivial[1] on Unix and practically
impossible on Windows.
[1] It's possible via os.openpty(), where available; the documentation
says:
Availability: some flavors of Unix
