-       * src/preproc/tbl/table.cpp, src/preproc/tbl/table.h: A try at the
-       new rule for block column allocation is now enabled by the new
-       "experimental" flag.  It doesn't work right as yet; there appears
-       to be some error in the computation of 3avail, the available line
-       length.  The purpose of this patch is (a) to make experimenting
-       with other formulas easy, and (b) leave the infrastructure for
-       flag 'experimental' in place for future experiments.  Do not
-       document any behavior associated with this flag!
-
-       * src/preproc/tbl/table.cpp: New table::count_block_colums()
-       method counts columns in the table that have T{ T} entries.
-       Requires the new parent field in the table_entry class.  Not
-       yet used for anything.
-       
-       * src/preproc/tbl/table.cpp: Initializers for table_entry()
-       and all its subclasses now receive a pointer to their parent
-       table and use it to set a parent field in the instance.  This 
-       changes no behavior in itself, because the parent field 
-       is not yet used for anything.  But there are plans.
+       A try at the new rule for block column allocation is now enabled by
+       the new `experimental' global option: The horizontal space up to the
+       right margin which is not used by columns without text blocks is
+       evenly distributed to the columns with text blocks.
+
+       It doesn't work right as yet; there appears to be some error in the
+       computation of `3avail', the available line length.  The purpose of
+       this patch is (a) to make experimenting with other formulas easy,
+       and (b) leave the infrastructure for flag `experimental' in place
+       for future experiments.  Do not document any behavior associated
+       with this flag!
+
+       * src/preproc/tbl/table.h: Include `stdbool.h'.
+       (table): Make `flags' public.
+       Add `count_block_columns' function.
+       Add `blockflag' array.
+       Add `EXPERIMENTAL' enumeration value.
+
+       * src/preproc/tbl/table.cpp (AVAILABLE_REG, COLCOUNT_REG): New
+       macros.
+       (table_entry): New member `parent' so that class and subclass
+       members can set a parent field.  Update all users.
+       (block_entry::do_divert): Handle `EXPERIMENTAL' flag.
+       (block_entry::do_width): Set the parent's `blockflag'.
+       (table::allocate): Handle `blockflag'.
+       (table::count_block_columns): New function.
+       (compute_span_width): Adjust AVAILABLE_REG.
+       (table::compute_widths): Handle COLCOUNT_REG and AVAILABLE_REG.
+
+       * src/preproc/tbl/main.cpp (process_options): Handle `experimental'
+       option.
