The problem arises when using tab completion. There are different cases.

(1) Suggestions are listed but from somewhere else after writing the colon.

julia> cd("C:[TAB]

I think it should go directly to C:\\.

(2) Suggestions are listed but somewhere else, also after a withe space or if there is some white space on the string. For instance one can have two different folders with similar names

julia> cd("C:\\Path With [TAB]

which sould suggest the two folders I created, "Path With Spaces" and "Path With More Spaces"

(3) Even weirder things happen when you try to switch between different drives, shuch as "C:" or "D:".
Sometimes it suggests or completes the path from another drive

julia> cd("D:\\FooFolder")

julia> cd("C:\\BarFolder")

julia> cd("D:[TAB]

It suggests what it is inside FooFolder. And if

julia> cd("D:\\FooFolder\\Folder With WhiteSpaces[TAB]

it lists what it is in BarFolder.

(4) Finally, I also found that if a single backslash is typed, then it doesn't write the sencond one needed

julia> cd:("C:\Fo[TAB]

julia> cd:("C:\FooFolder\\

(5) Extra bug. It doesn't autocomplete just after the dollar symbol.

julia> cd("C:\\Foo$[TAB]

prints all methods and so on.

I think we need a more precise list, but I don't have the skills to know how and why this may happen. Sorry. I tried to do my best.

PS, I'm not sure if this only happens on Windows. The whitespace and dollar bugs may happen also on Linux.
