NetBSD dstar 8.0_STABLE NetBSD 8.0_STABLE (GENERIC) #0: Fri Nov 30 13:53:15 PST 2018  scole@dstar:/home/scole/nbsd/cvs/8_0/obj/sys/arch/i386/compile/GENERIC i386
>Description:
When I login with tcsh and a terminal that is wsvt25, the cursor
always jumps to line 28.  My console has about 66 lines with the
GENERIC kernel and some nvidia card.

The other shells I tried (sh/csh/bash) work as expected, just drawing
on the next lines.  I believe my /etc/ttys is more or less the i386
default with ttyE1/ttyE2/ttyE3 turned on.  The "console" which is set to
vt100 works as expected.

I understand I could change all ttys to vt100 or vt220, but it would
be nice if tcsh behaved the same as other shells.

I'm using standalone-tcsh-6.20.00nb2 tcsh and my /etc/ttys:

ttyE3   "/usr/libexec/getty Pc"         wsvt25  on secure

>How-To-Repeat:
login with tcsh to a wsvt25 console terminal (with more than 25 lines?)

 tcsh doesn't use editline or curses and implements its own line
 editing functionality, so this probably should be either a pkgsrc PR
 or a bug directly against tcsh.
