vi: don't overwrite existing file
If the name of the file being written doesn't match the current
filename and the output file already exists vi should issue a
warning and not overwrite the file.
Because the test only compares the file names it's somewhat over-
protective. If the current file name is 'my_text' and the user tries
to save to './my_text' they'll be prevented from doing so.
