That's:
skip_all="reason"
test_done
Which we could spell as:
skip_all "reason"
Or whatever, if we wanted such a self-documenting helper.
There's no facility in TAP syntax to indicate in some special way that
you'd like to skip all remaining things once your test is already
running, the best you can do is just exit at that point.
I.e. the (very light amount of) special-ness (such as it is) is that if
the very first line of the output is "1..0 skip [...]" progarms like
"prove" will emit the skip summary as part of the output. See DIRECTIVES
