How about doing it this way:
*** ../vim-7.1.305/src/ex_docmd.c Sun Mar 16 16:02:47 2008
--- src/ex_docmd.c Fri May 30 21:56:21 2008
***************
*** 9300,9306 ****
break;
default: /* ":tag" */
#ifdef FEAT_CSCOPE
! if (p_cst)
{
do_cstag(eap);
return;
--- 9300,9306 ----
break;
default: /* ":tag" */
#ifdef FEAT_CSCOPE
! if (p_cst && *eap->arg != NUL)
{
do_cstag(eap);
return;

I've run this poem threw it, I'm sure your please to no,
It's letter perfect in it's weigh, my checker tolled me sew!
