patch: global -u on win32 with src root at drive root

[Kai Tetzlaff]

Hi,

i compiled global on win32 and tried it with a source tree which starts
directly at the drive level (root='D:'). In this case the chdir which
takes care that the search in 'global -u' starts at the root of the src
tree does not work on windows if there's no '/' at the end of the path.
If you change root='D:' to root='D:/' its working. So i changed
chdir(root) to chdir(get_root_with_slash()) in order to fix this. I
don't think this will cause problems for unix systems.

Could you consider adding the attached patch to the global sources?

BR,
Kai
