of identifiers to rule this out from being the first character of a
symbol which has no prefix. Recognize the ^ character as a token in the
NESTED state.
* lib.c (obj_print, obj_pprint): Render sys:qquote as ^.
* parser.y (choose_quote): Function removed.
(n_expr): Recognize '^' as quasiquote. Removed all the "smart quote"
hacks that try to make quote behave as quote or quasiquote, or try to
cancel out unquotes and quotes.

re-binding. C code now has to go through the dynamic environment lookup
to access things like *random-state*, or *stdout*. As part of this,
I'm moving some intrinsic variable and function initializations out of
eval.c and into their respective modules. Macros are are used to make
global variables look like ordinary C variables. This is very similar
to the errno trick in POSIX threads implementations.
* eval.c (looup_var, lookup_var_l): Restructured to eliminate silly
goto, the cobjp handling is gone.
(reg_fun, reg_var): Internal function becomes external.
reg_var registers a simple cons cell binding now, without any
C pointer tricks to real C global variables.
(c_var_mark): Static function removed.
(c_var_ops): Static struct removed.
(eval_init): Numerous initializations for streams, syslog, rand,
signals and others moved to their respective modules.
The new symbol variables user_package_s, keyword_package_s
and system_package_s are interned here, and the variables are
created in a special way.
* eval.h (reg_var, reg_fun): Declared.
* gc.c (prot1): Added assert that the loc pointer isn't null.
This happened, and blew up during garbage collection.
* lib.c (system_package, keyword_package, user_package): Variables
removed these become macros.
(system_package_var, keyword_package_var, user_package_var): New
global variables.
(system_package_s, keyword_package_s, user_package_s): New
symbol globals.
(get_user_package, get_system_package, get_keyword_package): New
functions.
(obj_init): Protect new variables. Initialization order of modules
tweaked: the modules sig_init, stream_init, and rand_init are moved
after eval_init because they register variables.
* lib.h (keyword_package, system_pckage, user_package): Variables
turned into macros.
(system_package_var, keyword_package_var, user_package_var): Declared.
(system_package_s, keyword_package_s, user_package_s): Declared.
(get_user_package, get_system_package, get_keyword_package): Declared.
* rand.c (struct random_state): Renamed to struct rand_state to
avoid clash with new random_state macro.
(random_state): Global variable removed.
(random_state_s): New symbol global.
(make_state, rand32, make_random_state, random_fixnum, random):
Follow rename of struct random_state.

function. This must not flush out more than one character out of this
small buffer, except when we are flushing out the last data.
The correct operation is predicated on the assumption that
a complete character can be pulled out. That's why we move the
buffer to the front after consuming it, and do not automatically
flush until there are four bytes.
(string_out_put_string): We loop the call to string_out_byte_flush
here because when a request comes in to write a Unicode character,
we flush all the bytes, even if the tail of those bytes forms
an incomplete sequence that turns into U+DCxx codes.
(get_string_from_stream): Use the same loop termination test
as in string_out_put_string, for consistency. In that function
it is needed to prevent infinite looping in the case when
the string_out_put_string is being called from string_out_byte_flush
and is thus re-entering it.

represent empty optional output clauses, distinguishing them from
missing clauses. This creates an ambiguity, so that an @(output)
block which puts out a single empty line is treated as empty.
Present but empty clauses are now represented by t.
* match.c (do_output_line): Check for t and bail.
(do_output): Check for t instead of (nil) and bail.
* parser.y (o_elems_opt2): Nonterminal deleted.
(out_clauses_opt): Empty case generates nil.
(req_parts_opt): o_elems_opt2 replaced by o_elems_opt.
(repeat_rep_helper): Function now keeps track of which
clauses were specified. For those that were specified, but
empty, it substitutes t.

the case that :vars is explicitly specified as (). In this
case, no bindings escape from the collect.

:vars () and yet counting on the variable to exist.

differences between expected and actual test output.
* parser.l (yybadtoken): Handle new terminal symbol, SPACE.
New rule for producing SPACE token out of an extent of
tabs and spaces.
* parser.y (SPACE): New terminal symbol.
(o_var): New nonterminal. I noticed that the var rule was
being used for output elements, and the var rule refers to
elem rather than o_elem. A new o_var rule is a simplified
duplicate of var.
(elem): Handle SPACE token. Transform to regex if it is
a single space, otherwise to literal text.
(o_elem): Handle SPACE token in output.
* tests/001/query-2.txr: This query depends on matching
single spaces and so needs to use escapes.
* tests/001/query-4.txr, test/001/query-4.expected: New test
case, based on query-2.txr. It produces the same output,
but is simpler thanks to the new semantics of space.
