chainlint.sed: don't mistake `<< word` in string as here-doc operator
Tighten here-doc recognition to prevent it from being fooled by text which looks like a here-doc operator but happens merely to be the content of a string, such as this real-world case from t7201: echo "<<<<<<< ours" && echo ourside && echo "=======" && echo theirside && echo ">>>>>>> theirs" This problem went unnoticed because chainlint.sed is not a real parser, but rather applies heuristics to pretend to understand shell code. In this case, it saw what it thought was a here-doc operator (`<< ours`), and fell off the end of the test looking for the closing tag "ours" which it never found, thus swallowed the remainder of the test without checking it for &&-chain breakage.
