Fix bugs in the isolation tester flex rules.

Browse Source 
Tom Lane pointed out that it was giving a warning: "-s option given but
default rule can be matched". That was because there was no rule to handle
newline in a quoted string. I made that throw an error.

Also, line number tracking was broken, giving incorrect line number on
error. Fixed that too.
