Description of problem:
If I try to write a shell script with "tcsh -e", it just doesn't work.
 The reason is because the file /etc/profile.d/colorls.csh contains
the line:

test -f ~/.dircolors

-- this sets the return code to be non-zero unless the file .dircolors
exists, and causes the shell to abort.

The workaround is:  erase the file /etc/profile.d/colorls.csh

The fix is to fix up this shell script so it doesn't rely on testing
the return code of the test command.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Create a shell script with the following contents:
#!/bin/tcsh -e
echo "Hi"

2. Try to run it.

Actual Results:  It doesn't print "Hi".

Expected Results:  Print "Hi".

To show what is happening in detail, use "#!/bin/tcsh -eX"

The 'test' commands can be avoided, but AFAICS
there is no way to avoid the egrep, and (tcsh -e) will exit
even if the egrep is executed while evaluating a controlling
expression of the 'if' command.

So what's the answer?

Don't run commands that could exit with non-zero exit code

To think again :)

The attached patch should fix it. It assumes GNU sed, which is probably
not a problem.

Sorry for reassigning, I have confused the file with lang.csh.

Thanks for the patch!  I've built this as coreutils-5.2.1-33.
