[PATCH] Fix prefixes list initialization in driver::OptTable ctor

[Mehdi AMINI]

Hi,

Please find attached a little bugfix for OptTable initialization of 
prefixes. The loop initializing the list of prefixes from the options 
list stops before the last entry. If the last entry in the options table 
uses a unique prefix, then it won't be parsed.

Thanks,

Mehdi
