That worked, thanks!

Any idea when that change happened? (I've been looking, but I haven't 
been able to find it).

We've got an older version on centos5 machines (so old augtool doesn't 
have a --version option) and the old syntax was working:

# augtool --version
augtool: unrecognized option `--version'

# rpm -qi augeas
Name        : augeas                       Relocations: (not relocatable)
Version     : 0.5.0                             Vendor: (none)

# augtool
augtool> set /files/etc/sudoers/Defaults[type=':nrpe']/type :nrpe
augtool> set /files/etc/sudoers/Defaults[type=':nrpe']/requiretty/negate !
augtool> save
Saved 1 file(s)
augtool>

# grep requiretty /etc/sudoers
Defaults    requiretty
# changed in order to be able to use sudo without a tty. See requiretty 
above.
Defaults:nrpe !requiretty
