comment typo, no real change
__wt_cache_full_check() can't have a NULL btree handle.
Panic if we get an illegal flag to the __wt_bt_cache_op function.
Verify shouldn't every modify the file -- don't bother checking for dirty
pages, just discard everything.   Should marginally speed-up verify, but
I'm doing it for clarity more than anything else.
Merge branch 'develop' into dirty-disable
