Inserting data, in general case (i.e. if the size may change), is
non-trivial. That is, one has to append a copy of the original file's tail
and then flush everything to disk again.So even if you do
:read !head -n 20 foobar.txt
and edit it, you still must do
:saveas temp
:!tail -n +21 foobar.txt >>temp
:!mv temp foobar.txt
to create a new version. And it does not look like some gain to me.
Regards,
Matvey
