Alexandre changed "strlen(xxx) > 0" in my first Patch to xxx[0]
So for your code above, simple change:
if(!name) {
to
if((!name) && (name[0])) {
The logic is the same: use the code-path, if name is NULL and use it
also, when the string is empty.
I send this type of patch yesterday and it's already in the tree.
The Commit-Message is here:

(i used (pName != NULL) to have a common style in this function)

Yes, it does, and it's important when we have a Program that depend on
this behaviour.

That's also a reason, why we have the Testsuite.
A specific Test changes "should match" to
"does not match (yet)" or "matches all the cases we tested".
The winedev-guide is nice to read. (see msg from James)
