OK, here's a followup question. If there's no problem with <lf>, then
why do we need to remove them? Does that justify uglifying the
existing code base? It seems like way 3.9 handles newlines creates a
lot more problems than it solves.
How often is removing <lf> an issue. Could displaying/hiding <lf> be
a feature that is toggled on and off? Couldn't <lf> be automatically
removed? This really doesn't seem like something humans should be
wasting their time doing. This is something that should be automated.
How did the <lf>'s get into the code base to begin with? Can't they
be blocked at the entry point? (of course, that doesn't deal with
the existing problems--but it seems odd that Squeak would allow me to
paste in invalid characters--especially if those characters cause
problems).
To me, displaying bad glyphs (at least with the source code in its
current shape) is a much worse problem than the issue of finding
rogue <lf>'s.
Unless there's a strong reason to the contrary, the editors should
follow the old CS advice. Be generous in what you accept, be strict
in what you transmit (in this case, in what you save).
You have yet to convince me that being able to see <lf>'s just so we
can delete them is a strong reason. For it to be a strong reason, you
need to show 1) that there is a concrete benefit to removing the
<lf>'s and 2) that always displaying the <lf>'s so they can be
deleted by hand is the best method for dealing with them.

Realistically speaking, I'll probably just go back to 3.8. However, I
would like to do my part to make Squeak better. Part of that includes
voicing my opinion when I think things are being changed for the worse.
To me, this seems like a poor design decision. I think there will be
a lot of unforeseen consequences (for example, making Squeak
incompatible with windows text files). Yes, there are ways to work
around the issue, but that's not the point. Not all users will know
how to work around the issue. Having a reasonable default behavior is
vital.

Sorry, I don't understand this comment at all.
My point was that now, in the 21st century, our systems should be
smart enough to open text files properly, regardless of which system
they originated on. For any modern text editor, newline
incompatibilities are a think of the past. They should be a thing of
the past in Squeak.
Remember, this is an issue that goes well beyond the Squeak source
code. There are many reasons why someone might want to open and edit
text files within squeak. This change will affect all of them, and
will make it much harder to use any text files that came from other
sources.
Compatibility is still a good thing. But that's just my 2 cents.
