That is not what i suggested though. I suggested '-e 1' to mean to default to the more common case: hw counters. I.e.: -e 1 == -e 0:1 -e 2 == -e 0:2 -e 3 == -e 0:3 ... sw counters could be specified only via the longer form. Anyway, most people will use symbolic names anyway (-e cycles, etc.), so i suspect the issue is mostly irrelevant.
