Error after calling git difftool -d with

Dear,

Incase filenames are used with a quote ' or a bracket [ (and maybe some more characters), git "diff" and "difftool -y" works fine, but git *difftool **-d* gives the next error message:

This issue is inside V2.10.x and V2.11.0. V2.9.0 is working correctly...

I am using git for windows and beyond compare 4.0 as difftool.

Best regards,

Peter
