This doesn't handle paginated results, but it fetches the 100 most
starred results so that's probably good enough for now.

Fixes Homebrew/homebrew#26566.

Homebrew currently recognizes "--head" during the install process, but
rather than actually fetch HEAD it just nags the user to use the
correct option.	Since we recognize the spelling anyway, this just
promotes the lowercase version to an official alias.

The example formula had no information about how
to find the current bulding directory. Now it has ;)

When patching read-only files, patch can try to check-out from
a VCS system when other conditions are met, such as environmental
variables being set.

Homebrew never wants to trigger this behavior, so pass --get=0.

When upgrading, if the only package to upgrade is a
pinned package, the output looked like that:
	==> Upgrading 0 packages, with result:

	==> Not upgrading 1 pinned package:
	<<package_name & version>>

The blank line is not beautiful. This commit fixes
the output and replaces with:
	==> No packages to upgrade
	==> Not upgrading 1 pinned package:
	<<package_name & version>>
