Definitely. This was just work in progress I posted while I figure out 
the test suite problem. I will add full commit messages when I complete 
the test cases. Thanks for reviewing, I will incorporate all your 
suggestions in the next version.

Right now that "char ref[1000]" code is rejecting refs on stdin if they 
are longer than 1000 chars or if they contain an ASCII NUL char in them. 
When I change this to strbuf_getline() should I be doing any similar 
checks, or do I just pass on whatever I read?
