printer: improve object formatting.
There is an issue with the printer in that it produces
output whereby objects continue on the same line after
a multi-line object, e.g:
(foo (foobly bar
xyzzy quux) (oops same
line))
rather than:
(foo (foobly bar
xyzzy quux)
(oops same line))
There is a simple fix for this: set a flag to force
a line break on the next width-check operation whenever
an object has been broken into multiple lines.
width-check can return a Boolean indication whether
it generated a line break, and so aggregate object
printing routines can tell whether their object
has been broken into lines, and set the flag.
* stream.h (struct strm_base): New member, force_break.
(force_break): Declared.
* stream.c (strm_base_init): Extent initializer to cover
force_break flag.
(put_string, put_char): Clear the force_break flag whenever
we hit column zero.
(width_check): If indent mode is on, and force_break is
true, generate a break. Clear force_break.
(force_break): New function.
(stream_init): Register force-break intrinsic.
* buf.c (buf_print): Set the force break flag if the buffer
was broken into multiple lines.
* hash.c (hash_print_op): Set the force break flag if the
hash was broken into multiple lines.
* lib.c (obj_print_impl): Same logic for lists.
* struct.c (struct_inst_print): Same logic for structs.
* tests/009/json.expected, tests/011/macros-2.expected,
tests/012/struct.tl, tests/017/glob-zarray.expected:
Update expected textual output to reflect new formatting.
