If fgets() succeeds (and returns a non-NULL value), you call new_text().
If it fails (either because of an input error or because the user
provided no input), you do nothing.
Is that what you want?
You print an error message if the user didn't provide a proper
command-line argument. Do you also want to print an error message if
the user didn't enter a message?
