spark: fix sha1
Fix `brew update` so that it doesn't show doubles

Under certain conditions, `brew update` will show doubles. It's a rare
edge-case, but if you have a tap where the name of the formula is identical
with the name of the insalled file, then you see output like this:

    ==> Updated Formulae
    aalib				   ssh-copy-id
    casperjs				   sshuttle
    jack				   telemachus/anytap/brew-any-tap
    mogenerator				   telemachus/anytap/brew-any-tap

I believe this should fix that.

doctor: Tweak git-clean suggestion for empty dirs

git clean -f is not enough. Needs `-d` somtimes to
handle cases when we rename a dir.
