[PATCH] Remove dead paren_level code

[Petr Písař]

Local variable `paren_level' in src/output.c:dump_line_code() is
initialized to 0, then compared to bigger than 0 leading to one dead
branch, then the variable is incremented with count_parens() return
value, and then the variable is use never more. Also count_parens()
has no side effect. Thus this patch removes this useless code.
