You are correct that the colon is the problem, but it is not a bug.
This is a restriction imposed by the design of Windows -- there are a
number of characters that Windows does not allow in filenames and the
colon is one of them. You can see a full specification here:
In this case, NTFS reserves the colon to denote alternate data streams.
There's nothing that rsync or Cygwin can do to change that.

You can use a managed mount as a workaround. This causes Cygwin to
encode characters that Windows won't allow in filenames with a quoted
version. It only works for Cygwin applications, obviously, as if you
look at the filenames using a non-Cygwin application they will look like
gibberish because of the encoding. It also shortens the effective
maximum file/path length because each character that is encoded
effectively takes three characters in the real filename.
