On pressing backspace+Enter, keep cursor indent

[AndrewRadev]

When I want to "exit" a block of code while writing it, I press <backspace>. For example, I'm writing this:

if foo
  bar
  # cursor

When I press backspace, I'll get something like this:

if foo
  bar
# cursor

But then, I want to leave some space after the block, so I hit <enter>. The result is that the indent of the new line is set to the one of the last non-blank line:

if foo
  bar

  # cursor

While this seems to be a minor issue, it trips me up all the time. I suppose I should get used to leaving the space first with an <enter>, but I can't seem to do so :). In python, the behaviour is exactly as I want it to be, so I took a cue from that indent file and I tweaked this one to work like that.

I understand there may be some specific reason to have it this way. If so, I have no complaints to rejecting this PR outright.

I also pushed a commit that makes the same behaviour work if the above line is a comment. To do that, I removed special handling of comment indentation. Everything seems to work okay after a few quick tests, but if someone notices any problems, please let me know.

Should this happen when I press o for new line + insert mode and type a #?

Seems like smartindent is meant for C -- it probably indents the # over there because it considers it a preprocessor directive. I've pushed a commit that unsets smartindent in coffeescript buffers.

Looking back at the history, this was actually the original behavior before 2a691d9/#69. I prefer the current behavior, but obviously it's a subjective thing, so at long last I've added a config knob coffee_indent_keep_current if you prefer it to work this way.

Thanks, this seems like it should please both camps.
