[tools] Flush stdout before reading input

Browse Source 
The last line of output (which is not terminated by a newline) was not
showing for me when running the merge script. We can either fix it by
specifying `flush=True` at the `print` statement, or flushing before
reading user input. The latter seems more future-proof.
