Andy Kopra 240cff4278 An output policy for the three commands, and @cond as a true special form
A snapshot of the development tree.  The substantial changes since the last one:

COMMAND OUTPUT POLICY.  The three commands display text in exactly three cases,
and each owns a stream: LOGGING under "-v" greater than 0 and an ERROR before
termination go to STDERR; OUTPUT THE USER ASKED FOR goes to STDOUT.  For ktext
that output is a document, so "ktext doc.kt -d | ..." is now safe -- logging
used to share the stream and land inside the document.  A bare command prints
its usage and succeeds rather than failing.  Colour is emitted only to a
terminal, per stream, and NO_COLOR is honoured.

"-v 1" reports every decision whose outcome you could not have read off your own
input: the klammerset that was loaded and from which file, a font's directory, a
":files" name's file, how "-o" was expanded.  Higher levels are the trace.

The commands no longer warn and continue: an anomaly is an error, described with
its location.  Two exceptions remain, each for a stated reason -- a condition
that is expected and temporary by design, and a judgment that is a heuristic
rather than exact.

@cond IS NOW A TRUE SPECIAL FORM, resolved at APPLICATION time rather than when
the file is read.  Two consequences for a writer:

  * a state variable reaches the predicate.  "@@@state Flag :value true @@@
    @cond *Flag* | T | F @" renders "T"; it used to see the literal "*Flag*" and
    silently take the false branch.  The document now behaves like a klammer
    body, whose arguments are bound before its conditionals are decided.
  * nothing in a discarded branch happens -- it is not read, not evaluated, not
    expanded.  An @eval in the branch not taken used to run anyway.

Its predicate relation is total and strict: true, True, 1; false, False, 0, and
empty; anything else is an error at the @cond rather than silently false.

@eval REACHING OUTSIDE.  ":shell" and ":haskell" now keep the command's standard
error out of the document (it appears under "-v 1") and treat a nonzero exit as
an error naming what the command reported.  A command that exits nonzero on
purpose -- "grep" finding no match -- says so with "|| true".

KLAMMER SETS.  Several combine: "--klammersets a b c" loads all three in the
order given, sharing one namespace, with the definition modes deciding
collisions.  "none" means none and may not be combined with other symbols.  A
klammerset with symbol X is declared in a file X/X.k, which is what lets two
sets require the same third set without loading it twice.

TESTS.  Four new suites: the kdiag command's interface, the @eval primitive's
contract with the outside world, and verbosity at both tiers.  Three suites
that could not run on macOS at all now do.

Assembled from dev commit 6c8ee6c22fca.

# target_list_test.sh — A klammer definition may name several targets.
#
# @@table.html,tex :: <body> @@
#
# One body, several targets. The list is SURFACE SYNTAX: the registry makes
# one definition per target named, so nothing downstream of registration knows
# a list was written. That is what these tests pin down — in particular that
# each member goes through the redefinition transition table on its own, so a
# list overlapping an existing definition is decided per target rather than
# all-or-nothing.
#
# Why the feature exists: a klammer whose body is an `@eval` cannot have its
# coverage derived (deciding which targets a Python function answers for is
# undecidable), so its targets must be DECLARED. Writing one definition per
# target would then duplicate the body. See notes/target_coverage.md.
#
# Two patterns are involved and must not be confused (mac/ktype.h):
# definition_begin_name — runs through commas; used ONLY for "@@<name>"
# definition_name — no comma; klammer applications, option names,
# "*arg*" variables, and the closing delimiters
# Case 14 guards the second: a comma next to an application is writer text.
#
# These are engine tests, so they use --klammersets none and define their own targets
# inline: a target is a Machine construct (@@@target), not owned by any
# klammer set.
#
# Usage: ./target_list_test.sh (needs KLAMMERTEXT_HOME set; ktext on PATH)
# Exit code: 0 if all tests pass, 1 otherwise.
