This is Getopt::Long's abbreviation handling; if the switch specified is a
unique abbreviation of one of the switches in GetOptions argument list, then
it acts as if the full switch was specified. See the section "Case and
abbreviations" in perldoc Getopt::Long. If you want to turn this feature
off specify 'no_auto_abbrev' as an argument in a call to
Getopt::Long::Configure.
