vacuumdb sentence

Hi,

Is there a reason to quote "jobs" at this sentence?

190 fprintf(stderr, _("%s: number of parallel \"jobs\" must be at least 
1\n"),
progname); 


AFAICS "jobs" is neither an identifier nor an option to justify the 
quotation. Also, another message a few lines above (correctly) does not 
use quotes.
