single-file: merge master and take test number 94

Master landed the change report (#721) and tests 88-93 while this branch was
open. Every conflict was both branches appending to the same tail, so each is
resolved as a union: htsopt.h keeps the change-report fields at their published
offsets and appends the single-file pair after them, and the lang files, GUI
templates and selftests carry both features' entries.
