GNU Parallel Bug Reports Parallel adding extra escaping?

[Thomas Johnson]

Parallel seems to add extra escaping to inputs with spaces:

    $ echo "2014-05-01 01:00" | parallel --dry-run foo \"{}\"

    foo "2014-05-01\ 01:00"

Note the extra \ after 2014-05-01. Is this intended behavior? Is there any way to disable it?
