+Hoowie!  Is that complicated.  Sounds fun though.  I just
+unmount the partition, get out a calculator, and adb the raw

     Any wizard worth his paycheck would take it one step further: adb the
block partition(don't have to unmount it first) and then use adb to modify
the ACTUAL directory block where the entry with the embedded NULL in it.
It's doable (I've done it on a V7 file system; I don't know if I'd want to
try it on a 4.2 file system). You wanna talk about complicated????
