This is OT, but "X:xxx" is not an error for the filesystem; at least in
many cases, Windows maintains a notion of a current directory per drive,
which means that you get this behavior:

C:\> cd books
C:\BOOKS> cd d:\rocks
C:\BOOKS> rem Note that we haven't gone anywhere...
C:\BOOKS> d:
D:\ROCKS> rem but the command had an effect anyway.
D:\ROCKS> type c:warandpeace.txt
...
D:\ROCKS> rem That was c:\books\warandpeace.txt, not c:\warandpeace.txt:
D:\ROCKS> type c:\warandpeace.txt
File not found
D:\ROCKS> rem Other relative paths can be used:
D:\ROCKS> cd c:nonfiction
D:\ROCKS> c:
C:\BOOKS\NONFICTION> exit

I understand if emacsclient can't use this style of filename (because of
technical limitations, or just for simplicity), or if I'm misunderstanding
the intent of the code, but I thought it important that its existence be
known.
