If Scratch is passed a file name on the command line for a file which does not exist, it treats it as read-only file, which is obviously wrong.
The Right Thing To Do is not obvious, though. Gedit creates the given files in such cases. For Scratch, which does everything to always show the current state of the file, I'd go with "No file = empty file". This means no infobars and creating the file on first edit. The use case for this would be continuously monitoring a file which is yet to be created (e.g. log file).
Disclaimer: this is the weirdest thing I did to Scratch so far.
