Previously the wrap guide would cause the
editor to scroll if the editor was narrower
than the wrap guide column without taking into
account whether any lines actually reach the guide.
Now the wrap guide only displays when either the wrap
guide column is less than the minimum width of the
editor layer or if the wrap guide column is less than
the entire width of the editor.
This corrects a regression when pattern matching
to the newline was added.
If the newline is never matched the loop still needs to
terminated so now when the position is before the newline
and the last match had no tokens the loop is broken out of.
The `load` method on the superclass will provide a general template for
loading the package's resource. Each subclass will be responsible for
loading resources in a manner appropriate for the package type. There's
some initial progress on loading TextMate settings as scoped properties,
translating the TextMate scope selectors to CSS-style atom selectors.
This makes the scoped property system mimic the behavior of CSS. When
there is a tie, the scoped properties loaded later in the cascade win.
I also optimize the scanning of all the properties, checking only those
sets of properties that have a value for the desired key path, to reduce
the need to match a ton of scope selectors.
We'll store all syntax-related global state in the `syntax` global. For
now, this means that all scoped properties will be stored here, as well
as all grammars.
Previously no gutter highlight was displayed unless
the selection was empty.
Now there is a separate CSS class for no selection
that changes the background color independently
from the foreground color.
You can pass a scope stack when calling `config.get`, which will prefer
settings under the most specific matching scope selector for the given
scope stack.
