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.
* tests/009/json.txr: Fixed to ^ quasiquote.
* tests/010/reghash.txr: Likewise.
* tests/011/macros-2.txr: Likewise.
* tests/011/mandel.txr: Likewise.
* tests/011/special-1.txr: Likewise.
* txr.1: Updated docs.
* genvim.txr: Revamped definitions for txr_ident and txl_ident so that
unqualified identifiers cannot start with # or ^, but ones with @ or :
in front can start with these characters.
* txr.vim: Regenerated.

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.
