The .. threading macro analyzes as a macro, not interop (jolt-c2l1 tail)

(.. x m ...) failed: the analyzer classified the .. head as a .method interop
call (method-head? matched any "."-prefixed name) and form-special?
(hc-interop-head?) also flagged it, so it never reached the macro check. Exclude
".." from both (the char after "." being "." means the threading macro, not
.method). Corpus 2690->2691. Re-minted.
