Bug in conditionals to assign values to variables?

Hi,

According to https://wiki2.dovecot.org/Variables you could use 

conditionals to assign values to a varible. The syntax is:

%{if;value1;operator;value2;value-if-true;value-if-false}

where any of the fields can refer to another field using %v or %{value} 

syntax.

The problem is that when I use a config like:

user_attrs = ...,=relpath=%{if;%u;eq;somevalue;valuetrue;valuefalse}

it works without any problem. But when I use:

user_attrs = ...,=relpath=%{if;%{user};eq;somevalue;valuetrue;valuefalse}

then it reports in logs:

Sep 28 14:23:22 myotis60 dovecot: auth: Error: var_expand_long(if;%{user}) failed: if: requires four or five parameters, got 1

anyway, the variable is correctly initialized, but I get the log.

Is this a bug?

PS: I'm running dovecot 2.2.33
