GPM is awful, tho', and this is an ugly hack. Why can't it just report
buttons like everyone else?
Another nice thing is that we don't seem to get the wheel events more
frequently than once in a second or so. Therefore it will work properly
only when you scroll slooooowly. :^)
This changes the init target to be idempotent: most importantly it will now
never overwrite a Makefile if it exists. Additionally 'make init' will
generate the .vimrc files. Yay, no more stupid 'added fairies' commits! ;)
Ditch the building of an archive (.a) in favour of linking all objects in a
directory into a lib.o file. This makes it easy to link in subdirectories
and more importantly keeps the build logic in the local subdirectories.
Note: after updating you will have to rm **/*.a if you do not make clean
before updating.
