oiiotool --wildcardoff / --wildcardon turn off and on numeric wildcard expansion

oiiotool --wildcardoff / --wildcardon turn off and on numeric wildcard expansion for subsequent command line arguments. You can have multiple on/off commands sprinkled among the arguments. The purpose is to be able to specify command line arguments with wildcard characters that are NOT expanded, for example if you are seeing a metadata attribute to contain an email address (whose '@' would ordinarily be recognized as a numeric wildcard).
