The tricky thing about drive letters is that C:foo is a relative path.
Unlike unix which has a single cwd, Windows has a cwd per drive and a
current work drive.

cd c:\foo       # Doesn't change current drive, just C:'s current dir.
cd d:\bar       # Doesn't change current drive, just D:'s current dir.
copy c:file d:  # copy c:\foo\file d:\bar

Win32 API calls and Perl internally accept '/' as a path separator.

For all URIs, path segments are separated by "/". Now, I suppose one could
stuff the entire file-path into a single URI-path segment, but I've never
seen that and "\" would have to be escaped (as it cannot appear in a path
segment unescaped).

And IIRC drive letters end up munged anyway, as file:///C|/path/goes/here

":" is now allowed and widely recognised.

Apparently, an older URL standard forbade unescaped ":" in path segments.
":" is not allowed unescaped in the first segment of a scheme-less URI, but
the provided URI has a scheme, and the drive is never in the first segment.
(The first segment is usually empty, but it can also be "." or a server
