ntpath.abspath and ntpath.normpath should preserve the input case for all
components of a path because they don't query the system for the real path. On
the other hand, ntpath.realpath in 3.8+ opens the path and queries the final
path from the system.
With drive-relative paths, ntpath.abspath does upper-case the drive letter.
That's due to the underlying GutFullPathNameW call on Windows (an API function
that normalizes a path as a string-only operation). We should just leave that
up to Windows instead of trying to impose consistency. The behavior could be
documented, however, along with other Windows behaviors such as per-drive
working directories with drive-relative paths, DOS devices (e.g.
"C:/Temp/con.txt" -> r"\\.\con") and stripping of trailing dots and spaces
(e.g. "C:/Temp/spam. . ." -> r"C:\Temp\spam"). These cases make
ntpath.abspath(path) more complicated than just the documented equivalent of
ntpath.normpath(ntpath.join(os.getcwd(), path))` on "most platforms" (i.e. most
POSIX platforms -- not Windows).
