New Code! (ultra-trivial edition)
I've pushed magicfilter up to version 2.3.g for trivially simple reasons. A while ago, I modified it so that if you had an appropriately modern libmagic.a on your system, magicfilter would build against that instead of building its own (old) version of libmagic, and a while after that I tweaked the make install rules and ended up breaking the install rules on systems with libmagic.a's.
So, New Code!, if by new code you include tweaks to configure.sh and the makefiles.
