Since you've specified the desired history size, bash tries to allocate
enough entries to hold all of the entries. The assumption is that this
will reduce the number of allocations/reallocations and the number of
times the history list has to be copied as it's reallocated. I suppose
I should cap the maximum value for which that occurs instead of trusting
the supplied max number of entries.
