Filebeagle hangs Vim when going above root directory

[genotrance]

Running Vim 8.0 on MSYS64 on Windows 10 in CMD.exe

When I start Vim and press "-" repeatedly, it goes up to the MSYS home directory (C:\Msys64\home) after which it hangs.

Likewise, if I start Vim on a file outside the MSYS home directory (C:\xyz\abc\file.123), pressing - repeatedly goes up to C: after which it hangs again and the Vim window has to be killed.

Not certain if this is a Vim issue or Filebeagle but hope you can find out.

The problem is caused by the lines:
let path_str = glob(l:current_dir.s:sep.'.[^.]'.a:glob_pattern)."\n".glob(l:current_dir.s:sep.a:glob_pattern)
and
let path_str = glob(l:current_dir.s:sep.a:glob_pattern)

The separator s:sep is not needed since it was already appended in the line:
let self.focus_dir = fnamemodify(a:focus_dir, ":p")

Simply replace those lines with:
let path_str = glob(l:current_dir.'.[^.]'.a:glob_pattern)."\n".glob(l:current_dir.a:glob_pattern)
and
let path_str = glob(l:current_dir.a:glob_pattern)
respectively.
