Yeap, I initially thought it would be tricky to implement in the
rather minimal Makefile, but it seems it wouldn't. Whoever, I still
find it useful that I don't have to run 'make' to test these, and I
think it's nice that people can download directly as the final name
('git-remote-hg'), and don't have to rename. And since these aren't
installed with 'make install' anyway, I don't see any big hurry.
