bug#45824: 27.1; term/screen.el not loaded when TERM=screen.xterm-256color

[Alex Hutcheson]

I just checked on two of my machines (running different distributions)
and didn't see anything that looked like it would cause problems. Most
were of the form "screen.something", and a couple terminfo files
included dots within version specifiers (e.g. st-0.8 and st-0.7).

The command I used to list all the relevant terminfo files was:
find /lib/terminfo /usr/share/terminfo -name '*.*' -type f -exec
basename '{}' ';' | sort -u

This worked on two Debian systems (one testing, one Buster), as well
as a macOS system.
