wake-format: Trailing whitespace in import statements not removed

[richardxia]

This is on wake 44.0.4.

$ cat >foo.wake <<-'EOF'
package foo

from wake import println 

def _ =
    println "Hello"
EOF

# Double check that there is indeed a trailing space on the import line
$ grep '\s$' foo.wake
from wake import println 

$ wake-format -i foo.wake

# Confirm that there is still a trailing space on the import line
$ grep '\s$' foo.wake
from wake import println

This is definitely a good thing to catch, thanks! To be clear, you've not seen it add spaces, just fail to remove them, right? That's actually weirder to me than if it was always generating the bad code since a lot of the formatter's architecture is built around throwing out the specifics of the input and always generating a consistent output.

Yes, just fail to remove them, at least as far as I have seen.
