And if it is supposed to be machine-readable with some backward
compatiblity property, then you could think about escaping ':', too:
that way, the old program reading your message will get the file name
wrong, but at least it will correctly parse the start of whatever comes
after the colon after the file name.

Just a thought, probably worth less than 2c...
