XLAT Parsing error.

[Arran Cudbard-Bell]

Hi,

Another small xlat parsing error,
alternate values arnt being parsed correctly in xlat strings involving 
modules.

update request {
             Supplicant-Flags = "%{sql_clients:SELECT 
EXPORT_SET(master.supplicant_flags,'1','0','',10) FROM `master` WHERE 
master.hw_address = '%{Calling-Station-Id:-null}' LIMIT 0,1:-null}"
}

expands to

SELECT EXPORT_SET(master.supplicant_flags,'1','0','',10) FROM `master` 
WHERE master.hw_address = '%{Calling-Station-Id:-null}' LIMIT 0,1:-null

when should expand to

SELECT EXPORT_SET(master.supplicant_flags,'1','0','',10) FROM `master` 
WHERE master.hw_address = '%{Calling-Station-Id:-null}' LIMIT 0,1

What would be really cool is if one query returned a null string a 
second query could be executed as an alternate, but i'm not sure how 
hard that would be to do.
