anchor: do not let piping and spelling transfer an anchor to the top

Browse Source 
Just let all anchors disappear when doing an external spell check or
formatting or piping the buffer through an external command, because
leaving just a single anchor on the top line is useless.

This fixes https://savannah.gnu.org/bugs/?58273.

Bug existed since commit 732cf887 from one month ago.  That code
causes an anchor to persist at the point where lines are removed.
