[Adduser-devel] Bug#367653: adduser: fails ungracefully with a null username

[Justin Pryzby]

Package: adduser
Version: 3.87
Severity: minor

# adduser ''
adduser: adduser: # 

I would expect some kind of error message, to the effect of:
|adduser: Please enter a username matching the regular expression configured
|via the name_regex configuration variable.  Use the `--force-badname'
|option to relax this check or reconfigure name_regex.
