visudo incorrectly reports Cmnd_Aliases are not in use

Binary package hint: sudo

Running visudo presents warnings that all Cmnd_Alias's are unused.

: linux13 27#; visudo
visudo: /etc/sudoers.tmp unchanged
visudo: Warning: unused Cmnd_Alias COMPILE
visudo: Warning: unused Cmnd_Alias GFX
visudo: Warning: unused Cmnd_Alias PACKAGE

visudo: Warning: unused Cmnd_Alias SERVICE_CONTROL
visudo: Warning: unused Cmnd_Alias SMART_CARD
visudo: Warning: unused Cmnd_Alias TEMP
visudo: Warning: unused Cmnd_Alias VPN

These Cmnd_Alias's are all part of another Cmnd_Alias, and in fact are in use. If using "-s", these warnings will not let you write the sudoers file out. It seems that visudo is not checking for nested Cmnd_Alias's.
