 Example: I have installed tcsh locally on my Solaris box, and I have a
 softlink from tcsh to -tcsh. The default shell for users is csh, and I
 exec -tcsh in my .login. Thus, in a ps style listing like yours above,
 the shell would show up as  .... -tcsh (tcsh).

 Under NetBSD, csh is really tcsh. Can't check the details now, I'd have
 to take out the gfx board to boot into NetBSD :-|

 It's described in the man pages for csh on eg. Solaris and Digital Unix,
 but it's not in the tcsh man page.
