The line-based protocol currently used cannot handle this properly, so
introduce this as a stop-gap measure - otherwise messages might be cut
off.
This makes it work for now, and the text is wrapped correctely for the
screen width in the TUI anyway - which is the only user of this so far.
Will be reworked properly later on.

Otherwise, when STDOUT is connected to a pipe, it will not get flushed
completely after each message, which might than hangs the installer UI.

This is used often, among other things also for some abort code, so
move the essence to the UI.
Allows to drop one global variable for proxinstall, which is a nice
side effect.
