I think what Nikos is trying to get as a result would rather need a 
change such as this:

Index: main.c
===================================================================
--- main.c	(révision 56597)
+++ main.c	(copie de travail)
@@ -264,7 +264,10 @@
  	}
  	else {
  	    if (!v_flag->answer)
-		fprintf(stdout, "\n");
+                if(vs)
+                    fprintf(stdout, "%s", vs);
+                else
+                    fprintf(stdout, "\n");
  	    else if (vs)
  		fprintf(stdout, "%s\n", vs);
  	}

which gives you:

 > v.db.select hospitals col=cat vs=,
cat

Just needs some cleanup to get rid of the last ',' at the end.
