Description of problem:
/etc/csh.login sets INPUTRC when it should not. 
It contains this test:
if ( -f $HOME/.inputrc ) then
        setenv INPUTRC /etc/inputrc
endif

the test is obviously backwards, if  $HOME/.inputrc does NOT exist
then INPUTRC should be set to /etc/inputrc

This seems to have been around since at least RH-7 ... 


Version-Release number of selected component (if applicable):
setup-2.5.27-1.1

How reproducible:
always

Steps to Reproduce:
1.chsh to csh or tcsh
2. touch ~/.inputrc
3. log on, and then do: 
 echo $INPUTRC                                                          
  
Actual results:
It will print:
/etc/inputrc

Expected results:
nothing should be printed, INPUTRC should not be set
