dovecot - Sep 2011 - quota percents

I've noticed that http://wiki2.dovecot.org/Quota/Configuration is out of
date, it says:

plugin {
  quota = maildir:User quota
  quota_rule = *:storage=1GB
  # 10% of 1GB = 100MB
  quota_rule2 = Trash:storage=10%%
  # 20% of 1GB = 200MB
  quota_rule3 = Spam:storage=20%%
}

but if you use the '10%%' notation, dovecot complains, and *also*
incorrectly:

dovecot: imap(test at example.net): Warning: quota root mail quota rule
Trash:bytes=10%: obsolete configuration for rule 'bytes=10%' should be
changed to 'bytes=+10%'

its incorrect because if you change it to what it suggests ('+10%') it
wont work because that wont be 10% more, rather, it is set to bytes=+10:

dovecot: imap(test at example.net): Debug: Quota rule: root=mail quota
mailbox=Trash bytes=+10 messages=0

clearly, that isn't right... so I guess it needs to be changed to
'+10%%', setting that provides:

dovecot: imap(test at example.net): Debug: Quota rule: root=mail quota mailbox=*
bytes=2211724 messages=0
dovecot: imap(test at example.net): Debug: Quota rule: root=mail quota
mailbox=Trash bytes=+221172 (10%) messages=0

that seems ok, its saying the Trash mailbox is set to have 221172bytes
(215 kilobytes) of quota. So, clearly
http://wiki2.dovecot.org/Quota/Configuration needs to be updated.

However, it doesn't seem to work in practice, because I have a user that
is at 99% of quota, with nothing in the Trash who cannot move a 77KB
message into the Trash without getting the quota_exceeded message and
refusing to move it.

so... how do I get this to work?

thanks!

Trash:bytes=10%: obsolete configuration for rule 'bytes=10%' should be
changed to 'bytes=+10%'
Right, fixed in wiki. Although this was only a warning, so it still
worked.

Well, that's a more complex problem. The %% escaping needs to be done in
dovecot.conf, but it doesn't need to be done elsewhere. If this said
that "use +10%%" and someone gives that in SQL user_query, it will
break. So I'm not changing the warning.

dovecot -n output?
