I have quickly tested locally on a Windows 10 enterprise, it seems that
you can go either on the c: drive or the C: drive and it respect the
case of the drive you typed.

Here is some lines from my tests:

C:\Users\Octobus\mercurial\test>hg log
('PATH', 'C:\\Users\\Octobus\\mercurial\\test',
'C:\\Users\\Octobus\\mercurial')

C:\Users\Octobus\mercurial\test>cd c:\

c:\>cd Users\Octobus\mercurial\test

c:\Users\Octobus\mercurial\test>hg log
('PATH', 'c:\\Users\\Octobus\\mercurial\\test',
'c:\\Users\\Octobus\\mercurial')

Where the printed line comes from:

print("PATH", os.getcwd(), os.path.dirname(os.getcwd()))

Hope it helps
