pgindent && weirdness

I just ran pgindent over some patch, and noticed that this hunk ended up
in my working tree:

diff --git a/src/backend/statistics/extended_stats.c b/src/backend/statistics/extended_stats.c
index 861a9148ed..fff54062b0 100644

         rightop = (Node *) ((RelabelType *) rightop)->arg;
 
-    if (IsA(leftop, Var) && IsA(rightop, Const))
+    if (IsA(leftop, Var) &&IsA(rightop, Const))
     {
         var = (Var *) leftop;
         cst = (Const *) rightop;
         varonleft = true;
     }
-    else if (IsA(leftop, Const) && IsA(rightop, Var))
+    else if (IsA(leftop, Const) &&IsA(rightop, Var))
     {
         var = (Var *) rightop;
         cst = (Const *) leftop;

This seems a really strange change; this
git grep '&&[^([:space:]]' -- *.c
shows that we already have a dozen or so occurrences already.  (That's
ignoring execExprInterp.c's use of computed gotos.)

I don't care all that much, but wanted to throw it out in case somebody
is specifically interested in studying pgindent's logic, since the last
round of changes has yielded excellent results.

Thanks,
