Summary: unbalanced braces in #define confuse scanner

Initial Comment:
Hi,

I found the problem in other case.

--------------------------------------------------------------
hirofumi@devron (linux3)[501]$ ls
test.c
hirofumi@devron (linux3)[502]$ cat test.c 
#define EPERM		1

#define for_nexthops(fi) { int fi;
#define change_nexthops(fi) { int fi;
#define endfor_nexthops(fi) }

int dn_fib_ioctl()
{
  return -EPERM;
}
hirofumi@devron (linux3)[503]$ cscope -l
>> 1EPERM
cscope: 2 lines
test.c EPERM 1 #define EPERM 1
test.c EPERM 9 return -EPERM;
>> q
hirofumi@devron (linux3)[504]$
--------------------------------------------------------------

In above case, cscope is not handling `tricky #define
derective'.
Cscope found the not global EPERM.

Thanks.

I don't there's anything we can really do about that... It's
already tricky enough to try not to fall over our own feet
at things like braces inside an #if' block --- at some
point, we have to stop.
