Lisp: its not just for geniuses anymore.

1. <http://www.sleepycat.com/docs/api_c/env_set_verbose.html>:
"Description: dbenv_get_verbose"
should be replaced with
"Description: DB_ENV->get_verbose"

2. <http://www.sleepycat.com/docs/api_c/env_set_verbose.html>:
"see the DB->set_errfile method"
should be replaced with
"see the DB->set_msgfile method"

is it really true that unless msgfile is set,
set_verbose will always fail?
why isn't it documented?!

Democrats, get out of my wallet! Republicans, get out of my bedroom!

set_verbose fails even when both msgfile and msgcall are set!
please help!
