t/chainlint: add chainlint "loop" and "conditional" test cases The --chain-lint option uses heuristics and knowledge of shell syntax to detect broken &&-chains in subshells by pure textual inspection. The heuristics handle a range of stylistic variations in existing tests (evolved over the years), however, they are still best-guesses. As such, it is possible for future changes to accidentally break assumptions upon which the heuristics are based. Protect against this possibility by adding tests which check the linter itself for correctness. In addition to protecting against regressions, these tests help document (for humans) expected behavior, which is important since the linter's implementation language ('sed') does not necessarily lend itself to easy comprehension.

chainlint.sed: improve ?!AMP?! placement accuracy When chainlint.sed detects a broken &&-chain, it places an ?!AMP?! annotation at the beginning of the line. However, this is an unusual location for programmers accustomed to error messages (from compilers, for instance) indicating the exact point of the problem. Therefore, relocate the ?!AMP?! annotation to the end of the line in order to better direct the programmer's attention to the source of the problem.

t/chainlint/*.test: don't use invalid shell syntax The chainlint self-test code snippets are supposed to represent the body of a test_expect_success() or test_expect_failure(), yet the contents of these tests would have caused the shell to report syntax errors had they been real test bodies. Although chainlint.sed, with its simplistic heuristics, is blind to these syntactic problems, a future more robust chainlint implementation might not have such a limitation, so make these snippets syntactically valid.

chainlint.sed: stop throwing away here-doc tags The purpose of chainlint is to highlight problems it finds in test code by inserting annotations at the location of each problem. Arbitrarily eliding bits of the code it is checking is not helpful, yet this is exactly what chainlint.sed does by cavalierly and unnecessarily dropping the here-doc operator and tag; i.e. `cat <<TAG` becomes simply `cat` in the output. This behavior can make it more difficult for the test writer to align the annotated output of chainlint.sed with the original test code. Address this by retaining here-doc tags.

chainlint.sed: drop subshell-closing ">" annotation chainlint.sed inserts a ">" annotation at the beginning of a line to signal that its heuristics have identified an end-of-subshell. This was useful as a debugging aid during development of the script, but it has no value to test writers and might even confuse them into thinking that the linter is misbehaving by inserting line-noise into the shell code it is validating. Moreover, its presence also potentially makes it difficult to reuse the chainlint self-test "expect" output should a more capable linter ever be developed. Therefore, drop the ">" annotation.
