No, and no.
The first and last lines in a text file may well be partial. If one
wants
a PS or LS in-between when concatenating them (assuming they are
of the same encoding), the LS or PS must be explicitly concatenated in.
(The result of reading, line-by-line, first file A then file B is not
always
the same as reading, line-by-line, the concatenation of files A and B.
I.e. readline does not distribute over concatenation, if you like that
kind
of formulation. Maybe you would like it to, but it doesn't, never has.)
