plugin updater doesn't like paths with spaces in them (at least on mswin)
<!-- bug reporting without issue template will be closed automatically -->

## Expected behavior, english is required
No deluge of error messages.
## The reproduce ways from Vim starting (Required!)
- Install SpaceVim on mswin from a gitbash terminal (neovim having already been installed).
- Start neo/SpaceVim (selecting dark mode).
- Exit nvim.
- Start nvim. <---- errors on plugin update
## Output of the `:SPDebugInfo!`
Unfortunately, I already reinstalled before thinking to report. No way to test until my plugins are out of date.

Seems like an issue with spaces in the path names. I reinstalled using regular cmd.exe and so far it is error-free.
