It is indeed being called.

The value of `str` after the first while loop is "83;40100;0" here. This is what
screen reports, and version is set to 240 in this case. Later, it calls
`terminal-init-xterm-activate-set-selection` if version is greater than 203.
Commenting this out fixes things for me again.
