chainlint: add test of pathological case which triggered false positive

This extract from contrib/subtree/t7900 triggered a false positive due to three chainlint limitations: * recognizing only a "blessed" set of here-doc tag names in a subshell ("EOF", "EOT", "INPUT_END"), of which "TXT" is not a member * inability to recognize multi-line $(...) when the first statement of the body is cuddled with the opening "$(" * inability to recognize multiple constructs on a single line, such as opening a multi-line $(...) and starting a here-doc Now that all of these shortcomings have been addressed, turn this rather pathological bit of shell coding into a chainlint test case.
