[Tcsh] $prompt and interactive shells

[Kimmo Suominen]

Hi Miguel,

The first thing I would check is /etc/csh.cshrc and /etc/csh.login to
see if they unconditionally set the prompt. At least FreeNAS used to
do that. (I don't currently have one running to check current TrueNAS,
though.)

Kind regards,
+ Kimmo
