There is a new syck bug that appears to be caused by the recent fix for 
Rich's bug report (Tue Nov 25 19:51:38 2003 UTC).  If I check out 
pre-Tuesday, I can't reproduce the error.

Here's a way to reproduce it:

$ ruby -e '1.upto(1029) do |num|; print "-\n  x:z\n  y:#{num}\n"; end' >big.yaml 

$ ruby -ryaml -e 'YAML.load(File.read("big.yaml"))' 
/usr/local/lib/ruby/1.8/yaml.rb:39:in `load': parse error on line 3088, 
col -1: `' (ArgumentError)
        from /usr/local/lib/ruby/1.8/yaml.rb:39:in `load'
        from -e:1

I made a small attempt to track down the problem, but it's getting late 
and I'm getting "stupider" with each passing minute. 

I noticed that we have gram.c, which is a bison-generated file, but we 
don't have gram.y.  Is that desirable?

Thanks,
Chad
