flag slit for reconfiguration and act on show

According to Peter Ganzhorn, there's a transparency issue when using an
autohiding slit, but I don't use a slit at all.
However, the explanations in the bug do make sense and this is just an
alternative approach on the problem (that does not require interim
showing)
