cmd/pprof: disable readline UI support for TERM=dumb In general, dumb terminal indicates terminal with limited capability. It may provide no support for special character sequences, e.g., no handling of ANSI escape sequences. Its input/output handling behavior may deviate from what's described in termios or terminfo. E.g., in the shell in emacs, even after successfully setting the terminal to raw mode, the terminal behaves as if it's still operating in canonical mode since emacs is doing input processing first. Readline support can be broken in various ways in dumb terminal mode, so we want to disable readline or advanced UI features. The easiest way to detect dumb terminal is to check the environment variable "TERM".
