I also used non-greedy .*? for the login portion since not sure if space could
be there and trying to minimize possibility of reacting on injected "from
<HOST>" somewhere within the trailing .*
Otherwise <HOST> regexp might swallow period in the sentence right after the address.
I have decided to enforce alphanumeric instead of switching to non-greedy +? ... because
I think it is closer to what we actually want here
This avoids duplication of code across fail2ban-regex and samples test
cases. This also now more neatly resolves the issue of double counting
date templates matches in fail2ban-regex.
In addition, the samples test cases now also print a warning message
that not all regexs have samples for them, with future plan to change
this to an assertion.
