tablecmds.c: right. Since 074c5cfbf

formatting.c: I don't see the problem.
if (Np->sign != '-') ... else if (Np->sign != '+' && IS_PLUS(Np->Num)) ...
You said that the "else" is never hit, but why ?
This is a Coverity report.
dead_error_condition:The condition Np->Num->flag & 0x200 cannot be true.
5671elseif (Np->sign != '+' && IS_PLUS(Np->Num))
CID 1501076 (#1 of 1): Logically dead code (DEADCODE)dead_error_line:Execution cannot reach this statement: Np->Num->flag &= 0xffffffff....
So, the dead code is because IS_PUS(Np->Num) is already tested and cannot be true on else.
