Since the break is in the middle of the line, it is not likely a
text/binary issue.  Much more likely that there is a change in the
terminfo/termcap for your terminal type or that you have a mis-match
between the value in TERM and the actual emulator you are using.

Your terminal type as found in the TERM varialbe needs to match the
emulator (which could be cygwin, xterm, rxvt, ansi, etc).  If these
match, then I would suspect a problem/feature in the terminal database. 
You might try different terminal names to see how they work.  Using the
following command line will set the varialbe for 'less' but not change
the current value:

   TERM=ansi less file_with_long_line

Then set 'export TERM=working_version' in your .profile where
working_version is the working version you hopefully found.  By the way,
you would probably also want to try it with your editor (assuming you
use something like vi) to be sure the new TERM value works with it too.

I hope this helps.
