This clearing of the screen is caused by the termcap capability 'ti'.

I tried this, too, but didn't like the t_ks effects. Since 'ti' (\033[?1049h)
clears the screen, I only cleared t_ti (with ":set t_ti=") and now the screen
isn't cleared anymore. This also means that the text for ":silent !{cmd}"
is correct the command ':silent !true' doesn't display anything and the
screen doesn't need to be redrawn, on the other hand the command ':silent !pwd'
outputs something and the screen isn't cleared, but needs to be redrawn.
Maybe Bram could add a small note like this: "If your screen is cleared
after issuing ":silent !{cmd}" and you don't like that, try this:
:set t_ti=
In this way your screen will not be cleared."
My system is Fedora 7 with a GNOME desktop and "gnome-terminal" as a terminal
emulator. My $TERM is "xterm".
$TERM is used by Vim to determine the capabilities for the terminal you're
using and 'ti' is one such capability in termcap; 'ti' is being referred to
as 't_ti' by Vim.
