So, hum. Shame on me, who believed that just by including s/screen, then it would include all the required terminfo files...
More seriously, this PR fixes that, at least.
I don't know at all how tmux works with terminfo, which terminfo files should we include for it ? Is it tmux, tmux.linux ?
If someone knows feel free to say here and I shall apply fixes as needed.
I haven't had any issues from tmux so far, but that's a separate issue. Merging.
