cyradm: how to quote mailbox (folder) names for special characters (space and '&') - not escaping

[Hasso Meyer-Jordan]

Hi Cyrus fellows!

cyradm (Cyrus 2.0.16):
Does anyone know how to quote mailbox (folder) names for special character 
matters (space and '&') in cyradm commands? Not escaping!

Like this (but it doesn't work):
setaclmailboxes "user.user1.Sent Items" adminuser lrswipcda

Neither double qoutes ("...") nor single quotes ('...') work.
By the way: escaping with backslash (\) for single special character(s) works 
well.


For script usage with files with lists of mailbox names escaping isn't easy - 
list files had to be inspected for special characters and the escaping of it 
had to be developed additionally.


Thanks, Hasso
