vi: saving unnamed file in readonly mode

Browse Source 
Suppose vi is started with the command 'vi -R', that is, in readonly
mode with no filename.  Attempting to save the file with 'ZZ' or ':w'
results in the message:

   '(null)' is read only

Skip the code which prints this if no filename was provided, thus
falling through to file_write() which gives the more helpful message
'No current filename'.
