A truncating write to tag drops the one newline that ends it
`echo X > tag` stored X and a trailing newline, which drew an empty tag row.
After a truncation the newline ending each write is held back until more
text follows or the open is released, so the one ending the whole of it is
dropped and any other stays; `>>` keeps what it is given.
