Bugfix: Fixed bug parsing transfer info files

The newline after the filename was included in it.

This was generally benign -- mostly these filenames are just displayed,
and the newline didn't matter.

But in the assistant, it caused unexpected dropping of preferred
content.

A characteristic of this bug is that the drop was displayed like this:

drop some_file
 ok

Logs/Transfer.hs
