The backslash addition is a feature of filename completion, and bash's
default word completion.  There isn't a really good way to have such
quotes stripped before handing the word to the completion function, nor
is there a specific option to have filename-like quoting applied to the
result (though the completion function can always add the backslash).

Because the colon is still a word break character, and readline passes `o'
to the completion function as the partial word to be completed.
