Tilde expansion doesn't work with escaped chars in pathnames

[Spakman]

Perhaps this will be helped by issue #4.

$ touch "/home/mark/one two three"
$ touch "/home/mark/one two zero"
$ ls ~/on<TAB>
one two three  one two zero   
$ ls ~/one\ two\     <-- Correctly completes first two words - <TAB> again doesn't work.
