Subject: [PATCH 16/74] Rewrite directory traversal allocation path so coverity
4210fa
 can grok it.
4210fa
4210fa
The things we do for our tools.  In this case, make the AllocatePool()
4210fa
happen outside of a conditional, even though that conditional will
4210fa
always bee satisfied.  This way coverity won't think we're setting fi
4210fa
to NULL and passing it to StrCaseCmp.
