I don't think so.

Earlier in 747a322 (grep: cast printf %.*s "precision" argument explicitly
to int, 2009-03-08), I casted the difference between two regoff_t you were
feeding to printf's "%.*s" as a length, introduced by 7e8f59d (grep: color
patterns in output, 2009-03-07), and 5b594f4 (Threaded grep, 2010-01-25)
carried that cast over without thinking.
