These were caused by keeping around a reference to the Squeezer
instance and calling it's load_font() upon config changes, which
sometimes happened even if the shell window no longer existed.
This change completely removes that mechanism, instead having the
editor window properly update its width attribute, which can then
be used by Squeezer.
There are plenty of legitimate scripts in the tree that begin with a
`#!`, but also a few that seem to be marked executable by mistake.
Found them with this command -- it gets executable files known to Git,
filters to the ones that don't start with a `#!`, and then unmarks
them as executable:
$ git ls-files --stage \
| perl -lane 'print $F[3] if (!/^100644/)' \
| while read f; do
head -c2 "$f" | grep -qxF '#!' \
|| chmod a-x "$f"; \
done
Looking at the list by hand confirms that we didn't sweep up any
files that should have the executable bit after all. In particular
* The `.psd` files are images from Photoshop.
* The `.bat` files sure look like things that can be run.
But we have lots of other `.bat` files, and they don't have
this bit set, so it must not be needed for them.

The boxes for the font and highlight samples are now constrained by the overall config dialog size. They gain scrollbars when the when a large font size makes the samples too large for the box.
Add two indent spec methods from editor and Rstrip to existing file.
Tests are not added for indent methods because they need change
in lights of 3.x's prohibition on mixing tabs and spaces.
* Only create CodeContext instances for "real" editors windows, but
not e.g. shell or output windows.
* Remove configuration update Tk event fired every second, by having
the editor window ask its code context widget to update when
necessary, i.e. upon font or highlighting updates.
* When code context isn't being shown, avoid having a Tk event fired
every 100ms to check whether the code context needs to be updated.
* Use the editor window's getlineno() method where applicable.
* Update font of the code context widget before the main text widget
This is done to compensate for the extra stack frames added by
IDLE itself, which cause problems when setting the recursion limit
to low values.
This wraps sys.setrecursionlimit() and sys.getrecursionlimit()
as invisibly as possible.
The initialize options are 1) add command line options, which are appended to sys.argv as if passed on a real command line, and 2) skip the shell restart. The customization dialog is accessed by a new entry on the Run menu.
