native behavior is very inconsistent

`>cd\windows`

(note that there's no space between "cd" and "\\"). is supported as command, but tab-completion on "windows" doesn't work

**but**

`>cd"\windows"`

(idem no space, but with quotes). isn't supported as a command, but tab-completion does work

since this relates to corner cases of user interaction, I'm not sure we want to mimic all these broken behaviors

for consistency I'd rather suggest that you use `WCMD_parameter` to split the edit line into separate words you can then work upon

this at least will provide consistency across all the code
