20850	Duplicate term insertion allowed after insertion with case differences	jazbek		"I've discovered a case where duplicate terms can be inserted with wp_insert_term(). Steps to reproduce:

1. Insert a term, i.e.
{{{
 wp_insert_term('USA', 'country');
}}}
2. Insert the same term, but with a different case, i.e. 
{{{
 wp_insert_term('usa', 'country'); // it's ok that this succeeds, because technically it *is* different (case-wise)
}}}
3. Insert the same term as in step 2. It should fail, but doesn't:
{{{
 wp_insert_term('usa', 'country'); // succeeds
}}}

This is because wp_insert_term() does the following:
1. Finds the first term in the db that matches the initial (non-unique) slug for the new term name
2. If the name of the found term doesn't match the new term name, then insert continues. In the example above, it's comparing all subsequent 'usa' term names to the first 'USA' term name and determining that it's ok to continue, when it's not because there are other 'usa' terms that it didn't look at."	defect (bug)	new	normal	Awaiting Review	Taxonomy	3.3.2	normal		has-patch dev-feedback	knut@… johnbillion kpayne@…
