Mark, I can not reproduce it. I ssh (with the key) from FrraBSD 9.3 box
(from either /bin/sh Bourne shell or /usr/local/bin/bash Bourne again
shell) to centos 5 (fully updated, bash shell), and my vi does behave as
expected, it is:

which vi
/bin/vi

vi -V

~
~                              VIM - Vi IMproved
~
~                               version 7.0.237
~                           by Bram Moolenaar et al.
~                 Vim is open source and freely distributable


I guess we need more detail about what you have.


Here is the file I open with vi:

cosmo ~]# cat test
# line 1 #
# line 2 #
# line 3
# line 4

Here is what I see when I open it with vi:

cosmo ~]# vi test

# line 1 #
# line 2 #
# line 3
# line 4
