Because it gives up on trying to understand any
control-character based escape sequences and just
lets everything through.  It thus looses track
of the correct column position.  These days,
the worst that can happen is that your terminal
emulator may need to be reset because of this.
In the past, a real terminal may have had a
printer hooked up to it and someone could have
attempted to send you a file containing escape
sequences that divert output to your printer.
A good pager would then protect you from this.

When you do, please tell me about any remaining
horizontal scrolling problems.  There may also
be problems with UTF-8 and searching, but this
can depend on the regexp library against which
"less" is linked.  I have addressed proper
UTF-8 handling from the input file and from the
search prompt, but haven't touched the search
implementation itself.

You wish there were.  There's much worst.

Here is a copy of the US Supreme Court decision
on George Carlin's famous "seven dirty words"
comedy bit:

   <http://www.georgecarlin.com/> then "Documents"
   <http://www.georgecarlin.com/dirty/dirty3.html>

He did say:

   "And, uh, bastard you can say, and hell
    and damn so I have to figure out which ones
    you couldn't..."

I think he's the man regarding this, so if he
said that "damn" is ok...
And this was some 33 years ago.
