Always start with an untouched screen that can scroll on printing "\r\n".
We can still clear the screen as needed.
Also drop support for hiding the cursor.

Now it's much more apparent why things are slow. You can see each repaint
happening. Already I fixed one performance bug -- in clear-rest-of-screen.
Since this subverts Mu's fake screen there may be bugs.
Another salubrious side effect: I've finally internalized that switching
to raw mode doesn't have to clear the screen. That was just an artifact
of how termbox abstracted operations. Now I can conceive of using termbox
to build a repl as well.
(I was inspired to poke into termbox internals by
http://viewsourcecode.org/snaptoken/kilo and
https://github.com/antirez/linenoise)

Disallow defining multiple globals at once.

Prefer preincrement operators wherever possible. Old versions of
compilers used to be better at optimizing them. Even if we don't care
about performance it's useful to make unary operators look like unary
operators wherever possible, and to distinguish the 'statement form'
which doesn't care about the value of the expression from the
postincrement which usually increments as a side-effect in some larger
computation (and so is worth avoiding except for some common idioms, or
perhaps even there).

Have $print in console mode rotate through the screen rather than simply
block at the bottom.

Experimental: kinda support $print in console mode.
It's not perfect and probably will never be, because 'cout' buffers
differently from termbox primitives, which can cause console-aware
newlines to show up before other (console-oblivious) prints, like in
this example program:
def main [
open-console
$print [abc], 10/newline
$print [def], 10/newline
wait-for-some-interaction
close-console
]
And then there's the problem that there's no way for cout to update
Display_column. So mixing $print and print will be confusing.
Perhaps we should just not mess with Display_* variables inside $print?
But then we'll only ever be able to see a single line of $print at a
time.

Always show instruction before any transforms in error messages.
This is likely going to make some errors unclear because they *need* to
show the original instruction. But if we don't have tests for those
situations did they ever really work?

Standardize quotes around reagents in error messages.
I'm still sure there's issues. For example, the messages when
type-checking 'copy'. I'm not putting quotes around them because in
layer 60 I end up creating dilated reagents, and then it's a bit much to
have quotes and (two kinds of) brackets. But I'm sure I'm doing that
somewhere..

Show more thorough information about instructions in the trace, but keep
the original form in error messages.
|
| |
|
|
| |
This should eradicate the issue of 2771.

Stack of plans for cleaning up replace_type_ingredients() and a couple
of other things, from main problem to subproblems:
include type names in the type_tree rather than in the separate properties vector
make type_tree and string_tree real cons cells, with separate leaf nodes
redo the vocabulary for dumping various objects:
do we really need to_string and debug_string?
can we have a version with *all* information?
can we have to_string not call debug_string?
This commit nibbles at the edges of the final task, switching from
member method syntax to global function like almost everything else. I'm
mostly using methods just for STL in this project.

- notes
bug in edit/ triggers in immutable but not master branch
bug triggered by changes to layer 059: we're finding an unspecialized call to 'length' in 'append_6'
hard to debug because trace isn't complete
just bring out the big hammer: use a new log file
length_2 from recipes.mu is not being deleted (bug #1)
so reload doesn't switch length to length_2 when variant_already_exists (bug #2)
so we end up saving in Recipe for a primitive ordinal
so no valid specialization is found for 'length' (bug #3)
why doesn't it trigger in a non-interactive scenario?
argh, wasn't checking for an empty line at end. ok, confidence restored.
