[Chicken-hackers] [PATCH] Fix buffer overrun in substring-index[-ci]

Dear Chickeneers,

the attached patch fixes a potential buffer overrun in
substring-index[-ci] I ran into today (pun intended). See commit message
for details. I included a regression test but I'm not sure whether it's
ideal because it adds a dependency on object-evict to the
data-structures tests. Alternative ideas welcome. While I was at it I
also added a range check for the start index argument and got rid of the
square brackets :-)

I guess this might warrant a CVE?
