After swallowing a here-doc, chainlint.sed assumes that no other
processing needs to be done on the line aside from checking for &&-chain
breakage; likewise, after folding a multi-line quoted string. However,
it's conceivable (even if unlikely in practice) that both a here-doc and
a multi-line quoted string might commence on the same line:
cat <<\EOF && echo "foo
bar"
data
EOF
Support this case by sending the line (after swallowing and folding)
through the normal processing sequence rather than jumping directly to
the check for broken &&-chain.
This change also allows other somewhat pathological cases to be handled,
such as closing a subshell on the same line starting a here-doc:
(
cat <<-\INPUT)
data
INPUT
or, for instance, opening a multi-line $(...) expression on the same
line starting a here-doc:
x=$(cat <<-\END &&
data
END
echo "x")
among others.
