Back in March, I sent a patch to Paul Placeway that would set the sl and el
variable properly.  There was a mistake in the source; tcsh was looking up
termcap capabilities named sl and el, instead of ts and fs.  Oops...

The fix is included below.  This was made from tcsh 5.18 (BBN) 2/20/90 pl 0.

Enjoy...
