Corinna Vinschen 34aded1f54 Fix check for empty locale string in newlocale
The original test is broken.  It tests for a NULL locale which
isn't just wrong, it simply can't occur at this point due to an
earlier check for a NULL locale string.  Thus, the locale info
for a category is never taken from the environment.

Fixes Coverty CID 153467.

Also, add comment.

Also, add some parens for readability.
