This actually fixes a rather obscure bug. This was failing to find
end of the string:
$ echo -n '[foo]' | dc

bc: remove "error after expression parsing" check
...
It is misplaced: caller knows better what can or cannot follow the expression.
Sometimes even caller's caller: "if (1) return a+b else..." -
parser of "return" does not know that "else" after it is valid,
parser of stmt does not know it either, - only parser of
"if" knows it!
The removed code balked on e.g. "{ print 1 }" statement.
This does not break any valid programs, but starts accepting some
invalid ones, e.g. "print 1 print 2" would work.

bc: partially rewrite parser, tests pass, ^C might be broken now
...
The entire control construct (if/while/for/funcdef) or {} block is
"eaten" by the corresponding parsing function, instead of maintaining
special "block flag stack" with magic bits in it, and returning to main
input loop after every inner statement (every input line, essentially).
This required moving line input deep into lexer - now zbc_lex_next()
triggers more reading when needed.
"block flag stack" is gone.
Correctness of ^C handling wasn't checked, might need fixing now.
if/else syntax is changed to match GNU bc: "else" can not be on
the next line (the rationale is that "if (1) 2" statement in interactive
mode should execute and print 2 instead of waiting for possible
"else ..." line).
This change fixes the following examples:
if (1) if (1) 1 else 2 else 3
if (0) 1 else if (1) 2
define w() { auto z; return 1; }

bc: rewrite "block flag stack" using simple realloc'ed byte array
...
Each access to current top flag took a function call + fetch of three data items
+ multiplication and some additions + and then following the resulting pointer.
After the change, it is: fetch pointer value + one byte access via this pointer.
