This is required for the property-list bundle to highlight
.plist files that maybe in XML or non-XML formats.
Also specify the cached buffer disk contents to grammarForFilePath
so fs.read doesn't need to be called again if the contents are
already read.
Previously the status was fetched twice, once for
if modified and once for if new.
Now the flags are fetched once and Git now provides
helpers to check the status flags directly for
modified and new status.
A confirm dialog is now displayed whenever a session
with a dirty buffer is closed so dirty sessions can now
be processed when 'editor:close-other-tabs' is fired.
Previously only the active editor session was prompting to
save dirty buffers before closing. This caused the confirm
dialog to not display when closing from a tab since the
Editor.destroyEditSessionIndex is used there.
Previously window.shutdown() was called multiple times
if window.close() was called since the shutdown handler
was also fired in the native window controller.
This prevented proper serialization of the RootView
from occurring when then window was closed via meta-w or
meta-W since it was called a second time when already
empty of packages and editors.
Previously if null was returned for the end of word position then
it was interpreted as 0,0 which would select the entire contents
before the current word instead of the current word.
Previously we were relying on the package module itself to have a
`name` field. But now that we're using `atom.loadPackage` to load up
packages, we can infer the name of the module from the name of the
package directory.
Using this new `abort` mechanism ensures that autocomplete's changes can never be redone, while eliminating the need to track operation counts explicitly.
When `UndoManager.transact` is called with no function, you later need
to `abort` or `commit` the transaction manually. This allows
transactions to last longer than the dynamic scope of the single
function passed to `transact`.
