Many legacy filesystems append version or similar identification to file names, often using ':' as a delimiter.
OTOH, ':' is a valid character in a file name (and in an extension) on many operating systems.
Trying to distinguish between those two cases on an operating system by operating system basis just doesn't seem possible. Better to only promise what we are sure can be delivered - in other words, Vladimir's suggested semantics.
