Hello.
docs/signatures.pdf specified two same wildcards for different purposes:
a? Match high nibble (high four bits). IMPORTANT NOTE: Nibble
matching is only available in libclamav with the functionality level
15 therefore please only use it with .ndb signatures, each followed
by ":15" (MinEngineFunctionalityLevel, see 2.3.4).
a? Match low nibble (low four bits).
I think this is typo...
