    _______________________________________________________

Details:

screen's maximum supported length for OSC sequences is around 768 characters.
After that, parameters within the sequence begin to appear literally on the
screen.

The OSC 8 hyperlink feature (see via bug 50952) recommends that URLs of length
up to 2083 bytes, an "id" of up to 250 bytes, and the necessary boilerplate
(the ";id=" + ";" characters) are supported.

In order to at least silently ignore OSC 8, without causing display problems
if an app emits a long URL, could the OSC size limit please be increased to at
least about 2400?
