Issue #2621

Using the CodeMirror-guttermarker and CodeMirror-guttermarker-subtle CSS
classes to give the markers their color.

Issue #2602

When using the measure div to measure a LineWidget with coverGutter: true,
set the parent's width to include the gutter. Otherwise, the widget will
be measured as if it were not meant to cover the gutter (it will be
measured at a narrower width).

Fixes #2611

Modified the lineWidgetChanged test to also test for #2611

This makes it work correctly when the hanging indent is different from the indent unit.

As described in the comment, there was actually an intermediate selection being created, which clobbered the middle-click paste buffer and thus resulted in a $ being pasted instead of the actual content the user wanted. It's still a mystery why you couldn't repro it, but my guess is that due to some configuration (maybe in your window manager) your system wasn't updating the paste buffer as eagerly as Debian and Unity do by default.

Remove off-by-one in vim when head is further forward in the document than the anchor, where vim's selection becomes 1 less than CodeMirror's. This was originally done because the cursor showed past the anchor and looked like an additional character selection.

It's intended to match a literal `{`, but that must be escaped as it's
a meta character in JS regex.
