Question about aname_do_match behavior on invalid patten

[Eric Diven]

Incidentally, this is consistent with aname_replacer(); do_replacement()
returns KRB5_LNAME_NOTRANS when regcomp() returns a non-zero result as
well. I suppose I have the same question about the behavior there as well.

Thanks,

Eric
