is_allowed question and possible bug

[jhh67]

I was looking at the is_allowed() method in mmer.h trying determine its purpose. The following line has a bug either in the code or the comment, not sure which. As it is the conditional matches against TT*.

if ((mmer & 0x3c) == 0x3c) // TG* suffix

should be

if ((mmer & 0x3c) == 0x38) // TG* suffix
