Subject: [PATCH] Remove dead paren_level code

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