And sure enough, sparse built from the git tree works as expected.

Fedora only packaged 0.5.0, which doesn't include the last few
dozen commits.  And they probably won't update until a sparse maintainer
sticks a v0.5.1 tag on it.  I suspect that other distros are similar.

Adding Christopher Li to the recipient list - any thoughts?
