I'd beg to differ.  Not opening Vala files in fundamental-mode is very
useful.

I've experienced the same.  I previously used the melpa importer, so as
to not pollute upstream with it, but given that a patch is needed, we
might as well add it properly.

Given my superior knowledge of Emacs Lisp (just kidding), I'd guess the
order of declarations is wrong.  Pull the defcustom before the other
thing and it ought to work.

Use the (let ((revision ...) (commit ...)) (package ...)) convention,
adding a note that upstream has no tagged release.  Base version
appears to be "0.1"
