The problem IMO is a didactic one.
Reading the manual, the user--that's me :)--keeps in mind three possible 
values.

`t'
`nil'
`never'

If he tries to set the variable according a chosen
value, he gets this menu:

"Never"
"If existing"
"Always"

Should he remember, that for "If existing" the variable
will be set to nil, if he checks the var afterwards?

Probably.

However, more easy seems to me a value-setting following
logical pairs

t <=> "Always"
nil <=> "Never"
conditional <=> "If existing"

Given this, the tags may helpfully indicate the value
being set.
