Robert,

Here's what happened:

"$*" vs. "$@" -- The former always produces exactly one string (even if 
there are no arguments to the shell procedure), if the shell procedure 
had more than one argument, a space is inserted between each in the 
resulting concatenated single argument. The latter form ("$@") produces 
as many strings as there were arguments to the shell procedure 
(including zero strings if there were no arguments to the shell 
procedure) and nothing is added to the contents of those arguments.

Here's what happens:

cd "`cygpath --unix "C:My Music"`"

I'm guessing your Cygwin root is the same as your C: drive root, so in 
this case you more or less incidentally get the result you want because 
your current directory was "/" (Cygwin) and "C:/" (Windows).

In this case, the unquoted backslashes essentially just disappear, 
since in each case the character they precede is not special.

If you want to use native Windows directory names (including both the 
drive prefix and the backslashes), you're not going get around 
explicitly quoting those names every time. If you have forward slashes 
(you won't get them from Windows Explorer, though), then you'll only 
need to quote the argument when there are spaces or other shell special 
characters, which is often enough.
