 _Black_ will add trailing commas to expressions that are split by comma where each
 element is on its own line. This includes function signatures.
 

-Unnecessary trailing commas are removed if an expression fits in one line. This makes it
-1% more likely that your line won't exceed the allotted line length limit. Moreover, in
-this scenario, if you added another argument to your call, you'd probably fit it in the
-same line anyway. That doesn't make diffs any larger.
-
-One exception to removing trailing commas is tuple expressions with just one element. In
-this case _Black_ won't touch the single trailing comma as this would unexpectedly
-change the underlying data type. Note that this is also the case when commas are used
-while indexing. This is a tuple in disguise: `numpy_array[3, ]`.
-

 One exception to adding trailing commas is function signatures containing `*`, `*args`,
 or `**kwargs`. In this case a trailing comma is only safe to use on Python 3.6. _Black_
 will detect if your file is already 3.6+ only and use trailing commas in this situation.
