block: Don't add trailing space in "Formating..." message

Change the message printing code to output a separator for each option
string before it instead of after, then we don't one more extra ' ' in
the end.

To update qemu-iotests output files, most of the times one would just
copy the *.out.bad to *.out. With this change we will not have the
space disliked by checkpatch.pl.
