terminfo capability for hyperlinks

[Bruno Haible]

Hi,

For about 7 years, this writeup explains how to use hyperlinks in
terminal emulators:

6 years ago, I wrote a library (GNU libtextstyle [1]) that makes use
of this feature on terminal emulators that support it. The problem is
determining the "support it": I did not find a terminfo capability
for it, at the time. Nor do I do now. So there still is this ugly code [2]
that looks at the value of $TERM, instead of using terminfo.

I also see that some programs introduce extra command-line options in order
to tell them about the hyperlink capability.

Would it not make sense to introduce a terminfo capability for this?
