Currently, sudo always strips out bash functions from the environment
even when env_reset is disabled.

When env_reset is *not* disabled, you can add specific bash functions
to the env_keep list.  For example, for a function call "ll" and
post-shellshock version of bash you could use the following:

Defaults env_keep += "BASH_FUNC_ll%%=()*"
