That version brings ES2016 support. However, the difference in syntax
highlighting is not distinguishable, because both `*` and `**` get the
same color.
Previously, the `^` marker was misaligned if the line above contained tabs.
Fixes T7282.
Note: This commit handles a very subtle edge-case differently: When the passed
in column number is larger than the length of the line. Previously, the `^`
marker would be faithfully placed at that exact column number. Now, it is placed
at the end of the line instead (after the last character of the line to be
precise). Ideally, we should define what should happen in edge cases, but that's
out of scope for this PR.
I'm extremely stupid and didn't commit as I go. To anyone reading this
I'm extremely sorry. A lot of these changes are very broad and I plan on
releasing Babel 6.0.0 today live on stage at Ember Camp London so I'm
afraid I couldn't wait. If you're ever in London I'll buy you a beer
(or assorted beverage!) to make up for it, also I'll kiss your feet and
give you a back massage, maybe.
