Especially since termcap is not involved in any way.

I suspect something in the tty driver.  But it's weird.

On a NetBSD/sparc, with a bwtwo RCONSOLE console, I see no problem on
the console, but if I run window(1) on the console and do it in one of
the windows, I see exactly what you describe.

When I rlogin or telnet from a SunOS machine to the NetBSD SPARC, it
behaves fine.  I suspect that under these circumstances, the tab and
its erasure are being handled by the SunOS tty driver....

So, what aspects of the tty driver (a) could affect this and (b) would
differ between the SPARC console and a window pty?  None come to mind;
tab erasure is handled by the generic tty driver code; see ttyoutput()
and ttyrub() in /sys/kern/tty.c....
