I've traced the problem to asearch() in agrep/asearch.c.  Evidently the
CurrentByteOffset is being calculated incorrectly there, *or* it is a
side-effect of the algorithm being used, I can't be sure.  With -i glimpse
uses a different algorithm (bitap I think) than without it.

Anyone familiar with agrep's algorithms?  Anyone have the two papers that
are mentioned in agrep/agrep.algorithms?
