I was envisioning just one function, that takes the terminfo symbolic
name of a capability and gives back the actual string.

Good point. I'm inclined to think that it's a good idea to provide this
even if we also provide the terminfo-accessing function, since there is
always going to be somebody who wants to do something that doesn't fit
into what (his) terminfo knows.
