fix a stale register value in dquotes.subx

How did things seem to be working until now?
- We were saving an address from the stack to stream.read
- When we read this address in skip-chars-matching:loop, we used to stop early

But now we've moved the stack to a larger address, one where the most significant
byte is set. When the stack address now gets to skip-chars-matching:loop,
it's treated as a negative number and we proceed through the loop. At which
point we try to index into the array using it.

No real test to be written to protect against this :(
