[sdiy] BC 547 / 2n3904 and lead reversal?

OK.. I just ordered a bunch of transistors to stuff in my Catgirl Synth
boards.. (I figure I'm not _really_ going to get moving on that project
until next year, but I think soldering boards would be a nice, mindless way
to escape from the stress of raising a two-year old, now and then)
Anyway: on Ken's site he mentions that the 2N3904 can be substituted for
the BC547, and the 2n3906 for the BC557 - but he thinks that the
substitutes might have reversed leads. I'm sensitive to this, because I
just botched a TR-909 repair for this very reason (Hi Trevor).
Can anyone confirm or deny that the leads are reversed on these
transistors?
