Bug#855223: debian-i18n: DDTSS rejects valid alias

[Thibault Polge <thibault@thb.lt>]

Package: debian-i18n
Severity: normal

When trying to create an account on ddtss, my usual alias "thblt" (lowercase letters T, H, B, L and T) is rejected with the message:

> Aliases are numbers, letters and underscore and at least 4 letters long, thanks.

Where it obviously matches these restrictions, being five letters.  After a (very) quick testing, it seems the actual minimum is six letters.

Thanks,
Thibault
