Bug 31259

Using the '>' operator to create a file larger than 2GB fails under tcsh
from RC2.  Error is "Filesize limit exceeded (core dumped)".  However,
using the 'limit' command reveals that no fsize limit is set.  Creating the
file using bash is successful.

This is a change from 7.0 -- it worked fine under 7.0-release.  I hadn't
tested this case with earlier betas, so I don't know when the problem was
introduced.

Here's a backtrace from gdb on the core file:

[dumpdisk@danton t]$ dd if=/dev/zero bs=1M count=3072 > foo
Filesize limit exceeded (core dumped)
[dumpdisk@danton t]$ ls
core  foo
[dumpdisk@danton t]$ gdb tcsh
