[dev] [st] Screen clearing problems

[Alexander Sedov]

Hi. I've noticed some odd screen clearing problems with TUI aptitude
(which switches to alternate screen when invoking dpkg, and instead of
clearing it just prints "0" and overwrites whatever text it has) and
transmission-remote-cli, which does the same upon exiting. This is
most likely due to mis-handled escape/wrong tinfo entry/"xterm
compliance". If anyone has the same problem with these or other
programs, please respond.
