get_adjacent_post doesn't exclude categories

[filosofo]

So get_previous_post and get_next_post both can't exclude categories.

It would be great to get this into the 2.5 branch, since it's such a simple fix.

#4304 marked a dup of this.

[TylerMartin]

The fix doesn't completely fix the problem. Even with the fix in place, if the post in the excluded category is also in any other category, the fact that it is in the excluded category is ignored and the post is not excluded from navigation (which is not the behavior of previous WordPress versions).

I think this error might be related:

2.6.1 has been released, moving to 2.6.2 milestone

[matt]

No patch for current problem, moving to 2.8.

db error described by scribu no longer should occur in trunk based on what I'm reading.

whether the behavior described by TylerMartin is correct is debatable.
