[Gretl-users] "outfile" makeover

The "outfile" command has undergone a slight makeover (but with backward compatibility preserved). This is in git and snapshots. * Creation of a new file (or overwriting an existing one) is now the default action. The --write option is still accepted but it's implicit unless --append is given. * The recommended way of terminating redirection of output is now "end outfile" (but "outfile --close" is still accepted). * The script editor now treats "outfile" as a block command, and indents the enclosed lines appropriately.
