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. function old new delta zcommon_parse_expr 40 32 -8 zbc_parse_name 509 494 -15 zbc_parse_stmt_possibly_auto 1678 1638 -40 bc_parse_expr_empty_ok 2025 1977 -48 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 0/4 up/down: 0/-111) Total: -111 bytes text data bss dec hex filename 981599 485 7296 989380 f18c4 busybox_old 981488 485 7296 989269 f1855 busybox_unstripped Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
