New bare @normalize directive: opts a definition into indent normalization
of BLOCK-FORM multi-line field values (first line whitespace-only, as
authored by opening a braced literal with a newline). The structural first
newline and a whitespace-only trailing line are dropped, the content
lines' common leading whitespace is the block's base indent, the first
content line is unindented fully and subsequent lines are re-based to the
standard 4-space continuation convention (deeper relative indents
preserved; whitespace-only inner lines become empty). Fields in a record's
-unindentedfields are exempt. Implemented as a resolve pre-pass over the
split records (private::normalize_records / rebase_multiline_value);
@normalize with options is an error.
Head-form values are never altered - their base indent is unknowable
(continuations uniformly at 6 may be base-4 with the deliberate +2
relative convention, or base-6 flush; re-basing would flatten the former).
The idempotence test caught exactly that on a file-style definition during
implementation, narrowing the user-confirmed re-base semantics to block
form only - which also makes @normalize a proven no-op on conforming
file-style definitions.
Consumer proof (punk 0.2.5, per the recorded user decision):
::punk::helptopic::define_docs converts from interim left-margin authoring
to indented block-form values under @normalize, dropping its
-unindentedfields declarations; 'i help' and 'i help_chunks' verified
aligned in punk902z src, including the blank-line separator in the
combined basehelp+extra block.
Tests: new normalize.test (5 tests: block re-base, block left-margin,
head-form boundary, exemption byte-exactness, file-style idempotence);
rendering.test P4 characterization stays pinned as the deliberate unopted
default with its text updated to reference @normalize. punk::args suite
186 pass / 1 pre-existing skip / 0 fail; punk::ns 53/53; full source-tree
suite 806 pass / 13 skip / 1 fail = exec-14.3 only (known baseline) - zero
regressions (tclsh 9.0.3). define doc documents the directive.
