[Users] strip_tail() string length?

[Daniel-Constantin Mierla]

Stripping is now possible with the new introduced 'transformations':
http://openser.org/dokuwiki/doku.php/transformations:devel

So if you want to strip last two characters of username in R-URI

$var(x) = $(rU{s.len})-2;
$rU = $(ru{s.substr,0,$var(x)});

Cheers,
Daniel
