The option to be prompted if open files are changed on disk does not work when editing a file which has been loaded via sftp.
Go to Utilities -> Buffer Options and set '"If open files are changed on disk" to "prompt"
Open a file via sftp
Edit same file via another editor (eg, vim)
Expected behaviour: jEdit should prompt that the file has changed.
Actual behaviour: No prompt is displayed.
jEdit 4.5.2 Server mode using Java 1.7.0_09
For comparison, the prompt is displayed correctly if the file being edited is accessed locally on the same filesystem.
