Tracing through (shell-quote-argument "c:/dropbox/org/personal.pdf"),
system-type is windows-nt
(w32-shell-dos-semantics) returns nil
This result occurs because I'm using (Cygwin) bash as my shell inside Emacs, not the Windows default, cmdproxy.exe. It's therefore true that my shell does *not* expect DOS file names (and gets very upset when you pass it a backslash...), but escaping the ":" seems to cause problems because now ":" is taken to be part of the file name, I think, rather than part of "c:", the name of the (Windows) disk.
