linter: do not pause when there are no messages for unopened files

Return immediately to editing mode when there are no messages for
the original file and the user does not wish to open any of the
included files that do have messages.

Also, reword the message that the linter gives then, and leave it
on the status bar (just like when Cancel is pressed).
