Summary: anydbm and 'n' flag

Initial Comment:
 When a 0 length file exists and anydbm is asked to
create a new database with that file name via the
anydbm.open(fn, 'n') call, the call fails as whichdb
detection fails.

whichdb should not be invoked with the 'n' flag, since
the purpose of this flag is to always create a
database, not only if it is missing.

This bug prevents creating a secure temporary file with
mkstemp and then uisng that file to open a database. 
The workaround is to unlink the file then call open,
but this is leaving a small hole.
