It'll only unlink a shadowing file _if and only if_ it is installing a new
file.  So if you just run "./Build install uninst=1" and nothing has
changed, then nothing gets unlinked.

I don't know if this is correct, but that's the deal ;)

Also, for extra fun, note that EU::Install prints messages like this:

## Running 'make install UNINST=1' will unlink $plural for you.\n

direct to STDOUT.  It'd be nice to catch that and rewrite it in M::B
language, but what an annoying PITA.
