Which string capabilities need script interpreation?

[Florian Weimer]

I'm trying to figure which string capabilities in terminfo files need
to run through the script interpreter during output.  Is this
information available somewhere?  Type information for the script
parameters would also be nice.

What about the string capabilities that need to be processed for $<…>
delays?  Are those marked with P in the terminfo manual page?

(Not sure if this is strictly an ncurses question, but I don't know
where else to ask.)
