I'm not finding it easy to understand what's going on from your
description, but if I understand aright then:
In case A: you press return in the middle of a line, the line breaks, the
second half and all below drop a line, and the second half begins at the
left of the screen.
In case B: you press return in the middle of a line, the line breaks, the
second half and all below drop a line, and the second half begins
vertically below where it was before.
If that's the case, then in case A your screen display is executing a
CR-LF combination, while in the second case it is executing a LF only.
Quite where this arises is anyone's guess, since the relationships between
keyboard input, file contents, and screen display depend on a variety of
translations carried out internally.
Normally, for keyboard input to a text file in any editor, the CR key
inserts a LF into the file (the standard UNIX end-of-line delimiter).
Normally, when a text file with LF EOL delimiters is output to screen, the
LF is translated into a CR-LF pair.
So case A looks normal, and case B looks like a failure to translate
LF->CR-LF on output. This is possibly an stty problem: try giving the
command
stty -a
in the relevant terminal, and compare the output with what "man stty"
says.
God luck,
Ted.
