Regex ungreedy modifier "U" breaks formatting

[h4cc]

The new Regex ungreedy modifier at the end of a regex "U" breaks formatting. The old value was/is "r":

ungreedy (U) - inverts the “greediness” of the regexp (the previous r option is deprecated in favor of U)

Examples:

~r/foo(.*)bar/i is ok
~r/foo(.*)bar/iU breaks formatting

It's a new feature for Elixir, so it'll count as an enhancement even though you experience as a bug.

This will be a port of elixir-lang/elixir#2774 for cross-reference.
