Trailing spaces not removed in multiline comment block

[mhernand40]

Adding · to the code snippet to visually represent spaces. Let's say we have the following code:

/*·
·*·©·Your·Copyright·Here
·*/

package·com.foo

class·Foo

Expected Behavior

Ktlint should be able to flag and remove that trailing space on line 1.

Observed Behavior

The trailing space remains, Ktlint does not complain about it nor does it strip it when running the formatter.

Steps to Reproduce

1. Paste the above code in a basic text editor (IDE may auto format if you paste it there and save)
2. Run Ktlint against the code above.
