Comment (by ncohen):

 Hello,

 > In [comment:322] Jeroen agreed above that 319 was in fact ok.

 Many times in the past I had to fix code which accepts a `**kwds`
 and did not check that what it contains is actually read. This
 lead to silent errors or wrong output, and so I immediately
 things like `global_options` as the highway to bugs.

 Jeroen noted that this variable is actually used somewhere else,
 so I guess it probably should not be removed in this ticket. My
 comment at [comment:319] still need to be adressed, however, as
 there is no documentation for this parameter. Please make it
 explain the uses of this flag, possibly by pointing to some other
 part of the doc if it is already explained somewhere else.

 As the method appears in this branch, I see no reason to let it
 be corrected in a future ticket.
