Subject: Let's hope, check_path() is now working properly.
X-Git-Tag: version_2_3~3
X-Git-Url: https://git.p6c8.net/devedit.git/commitdiff_plain/0fb9dcffcc2a1be81de150bae084e195c5f66658?hp=dff53f21c8fccc7585f785fec893a5773e78a1b6

Let's hope, check_path() is now working properly.
Maybe we should switch to Win32::GetFullPathName() on Windows...
