Fix open-new-line command for CRLF, as well as other bugs.

Fixes #363.

I set out to fix issue #363, but after fixing it discovered some
other things were wrong with the command while testing.  In
summary:
- #363 was because it was still assuming a line ending width
  of 1 char in its indexing calculations, even when actually
  inserting CRLF.
- Aside from #363, it actually needed to set `line_end_index`
  to zero for *all* calculations that use it when line == 0,
  but it was only doing so for a single calculation.
