It seems like there is an established practice of using low case
characters for hex encodings sent by stubs - otherwise 'm' request
would never work correctly. So, this is not an issue at all, unless,
you would tell me that existing implementations of qRcmd break
this one too :).

BTW, I got it while working on v0.2 of protocol spec, I was quite 
surprised that the positive impact of this exercise was that immediate.
