  M src/document.c

  Log Message:
  -----------
  Make document_save_file() show the Save As dialog when necessary

Previously an error message was shown if doc->file_name is NULL.

The Save As dialog is now shown if the document does not have an
absolute path. This is because the user should confirm where to save
the document in this case.

Although this changes plugin API behaviour, it seems the best way to
ensure the Save As dialog is always shown when needed so the user
knows where the document has been saved.
