If the settings requires an impossible way to use whitespaces, the
settings is buggy, and it generally would be better to correct the
setting before moving on.

I am curious to know in what situations this new behaviour can be
seen as an improvement.  It may allow you to go on _without_ fixing
such a broken setting, but how would it help the end user?  If the
user set both of these mutually-incompatible options A and B by
mistake, but what the user really wanted to check for was A, picking
just one of A or B arbitrarily and disabling it would not help, and
disabling both would not help, either.  But wouldn't the real source
of the problem be that we are trying to demote die() to force the
user to correct contradictiong setting into warning()?

Thanks.
