Windows path with space

[tzws]

for example, there's project under c:\workspace\project 1\src.

When I typing 'tabnew c:\workspace\project ', it won't sugguest 'c:\workspace\project 1', but files under cwd.

When I typing 'tabnew c:\workspace\project\ ', trying to escape the space character, it suggests

If I type double '\', 'tabnew c:\workspace\project\ ', trying to escape the space character, it suggests nothing.

this may related to previous issue I mentioned: https://github.com/hrsh7th/cmp-path/issues/31

If I start with nvim -u NONE, type 'tabnew c:/me/ccw/ccw\ ', here use unix path delimiter, and use '' as space escaper, and press type, it will promots:

PR welcome

I updated to the latest version. It seems if I start with cwd, using unix directory delimiter and space are handled correctly. But if I start with c: drive, there's some trouble.
