This does *not* include newlines. Doing this makes it possible to double-click regions of whitespace to select them just as you can select a word. It also makes word movement bindings behave similarly to TextMate.
Now that the cursor is hidden at the end of a selection, it's counter-intuitive for the commenting to extend to the next line since there's no visual indicator that the cursor extends to that location.
Now, we maintain md5 signatures for the on-disk and in-memory contents of the buffer. Whenever either contents change, we recompute the signature and store it on the buffer. We can tell if the buffer is modified by comparing these signatures. When the disk contents change, we compare the memory and disk signatures *before* recomputing the disk signature to determine whether to update the buffer or mark it as a conflict.
This metadata will be used to record the indentation level of the first line when copying multiple lines of text to the pasteboard. The pasteboard takes the md5 of the pasted content when writing, then when reading it associates the last written metadata only when the signature matches the previously written value.
When an open bracket is inserted, an anchorRange is created. When a closing bracket is inserted, and its position matches the end of one of the anchorRanges, the closing bracket is not inserted and the cursor moves right.
When we actually want to attach the root view in window-bootstrap.coffee, we call `window.attachRootView(path)` instead of calling `window.startup(path)`. Having `startup` called automatically means we can be sure any code we add there runs in every environment (including benchmark and specs). This is where we do things like setup the global keymap, parse text mate bundles and themes, and establish the window close handler. Any globals other than the root view that we want to be available in all environments should be established here. Right now that's just the keymap, but soon I want to add a global pasteboard.
If we're pasting multiple lines starting inside an already existing line, we never want to auto indent. We should just take its existing indentation level. Also, we strip the leading whitespace off the first line we're inserting, assuming it's already being represented by the indentation of the line we're onto which we're appending it.
Also, when some lines are *less* indented than the first line, it might not be possible to outdent them as far as they originally were relative to the first line, so we do as much as possible.
