If Mathematica is doing anything to make the frontend formatting simpler, I
dread to think what it would otherwise be.  What Mathematica does is quite
amazing.  Formatting  mathematical expressions on the fly is no mean feat.
I suspect the Windoze version is a bit more polished than the Linux

I've had several format related problems.  One that can really be annoying
is that code for packages will sometimes not work because something is
wrong in the formatting. In particular, I've noticed it doesn't like any
blank lines after commas; and even more troubling is that it sometimes
misbehaves because /something/ (I know not what) is hidden at the end of a
line.  If I delete and restore the newline, code that wouldn't work
correctly will start working.

That can be very frustrating to a person who, like me, doesn't have a solid
mastery of the language, because I spend a lot of time changing things that
are not causing the problem, and I form false ideas about what works and
what doesn't.

Another nifty gotcha is what happens when you put a definition after its
point of use in a package.  If there are any symbols from another context
used by the command, they are introduced into the Global` context and
shadow the intended symbol. The good thing about that problem is that it
can actually be understood, and, in fact, makes a bit of sense.

I don't know if there is a way to do this.  I've been meaning to look into
it before asking on the newsgroup, but I haven't had time.  Does anybody
know if there is a way to save a Cell expression in "raw" form without the
meta-layer of quotations, and in such a way as to preserve the hiddent
semantics such as TagBoxes?  IOW, I want it to look as it would if I had
typed it in Emacs.
