Hi.

    #
    # ~/.bashrc
    #
    echo Im in .bashrc >&2

RHEL 6.0, bash 4.1.2
    $ ssh localhost 'ps -f $$ && true'
    Im in .bashrc
    UID        PID  PPID  C STIME TTY      STAT   TIME CMD
    git      22295 22294  0 08:29 ?        Ss     0:00 bash -c ps -f $$ && true

Archlinux, bash 4.2.42
    $ ssh localhost 'ps -f $$ && true'
    UID        PID  PPID  C STIME TTY      STAT   TIME CMD
    il       26539 26538  0 08:26 ?        Ss     0:00 bash -c ps -f $$ && true


What can couse this? Manpage says: "Bash attempts to determine when it
is being run with its standard input connected to a network
connection". Is the detection broken?
