execute: stay on the same line number when filtering the whole buffer

Browse Source 
When the filter command makes just small, per-line changes, keeping the
cursor at the same line number allows the user to observe the effect of
the changes -- which is not possible when the cursor gets moved to the
end of the buffer.

This partially fulfills https://savannah.gnu.org/bugs/?57248.
