got: flush stdout before printing the error in main()

Since standard error is unbuffered, it could happen that the error
string is printed immediately while the output from the subcommand
is stuck in a buffer and written later.  So flush() standard output
before printing the error message.

Problem reported by naddy@, ok stsp@
